Marshall PlanApril 3, 1948

Foreign Assistance Act of 1948(Also referred to as the Economic Cooperation Act and the European Recovery Act)

• Grew from realization that slow recovery from war devastation in Western Europe would leave the region weak and subject to Communist incursion

• US leadership did not want a repeat of post- World War One conditions that contributed to the Great Depression and rise of Fascism.

• Marshall publicly presented idea in Harvard commencement address (June 5, 1947)

• Provided $12 B in recovery aid (Value in 2005 $: $555 B per GDP share)

• Major factor in Western European resistance to Communism

Nuclear Targeting Theories

Counterforce

Countervalue

: target warfighting capability

: target cities and industry

Page 22: Lessons 34 - 45 Review Slides

Nuclear Targeting Strategies

Truman: Countervalue

• US had nuclear monopoly, then preeminence

• Believed nuclear weapons most valuable against cities

Colonel John Osgood, USA, RetiredUnited States Nuclear Strategy 1945-1995

Eisenhower: Counterforce

• Soviet nuclear weapons became a concern

• Massive retaliation was public doctrine

Kennedy/Johnson: Flexible Response

• Public face: assured destruction (countervalue)

• Counterforce (war fighting) retained as an option

Page 23: Lessons 34 - 45 Review Slides

Nuclear Targeting Strategies

Nixon: Counterforce

• Publicly promoted position

• Developed warfighting weapons (MIRV, ABM)

Colonel John Osgood, USA, RetiredUnited States Nuclear Strategy 1945-1995

Carter: Counterforce

• Pursued decapitation strategy (targeted C3, leadership)

Regan/Bush: Counterforce

• Combined counterforce and strategic defense

• Blended arms negotiations (SALT) with SDI

Page 28: Lessons 34 - 45 Review Slides

Causes of the Cuban Crisis

Soviet Union threaten by US strategic missiles in Europe• Felt they were falling behind in arms race

Castro feared an invasion of Cuba by U.S.• Approved deployment of Soviet missiles to Cuba as a safeguard

Page 29: Lessons 34 - 45 Review Slides

Crisis ResolutionOctober 28, 1962

After exchange of messages, Kennedy & Khrushchev reached a confidential agreement:

• US will remove IRBMs from Turkey, Italy

• USSR will remove missiles from Cuba

• US pledged not to invade Cuba

• USSR agreed not to publicly reveal removal of IRBMs

Page 30: Lessons 34 - 45 Review Slides

Significance of Cuban Crisis

Kennedy gained prestige for having defused the crisis but widen trans-Atlantic gulf for not consulting with NATO allies

USSR lost some stature in Third World to China

Superpowers learned valuable crisis management lessons

Nuclear disarmament received increased emphasis

US Flexible Response doctrine validated

Characteristics:• Integrated military conflict and political conflict

Page 34: Lessons 34 - 45 Review Slides

Strategy of Revolutionary War

Phase I: Targeted state stronger militarily

Phase II: Rough military parity

Phase III: Revolution stronger than targeted state

• Revolutionaries avoid combat• Guerrilla war: raids, ambushes, sabotage, terrorism• Political conflict predominant

• Combined guerrilla and conventional war• Military and political conflict equally important

• Revolutionary forces go to totally conventional war• “General Offensive” linked to political “Great Uprising”

U.S. Attitude Toward Vietnam

Eisenhower (1954-1961): US Military Assistance • Trained ARVN to resist cross-border invasion

Kennedy (1961-1963): Counterinsurgency • Resisted by US military leaders

Johnson (1963-1969): Limited War • Attempted to force North Vietnam to negotiate

Nixon (1969-1973): Vietnamization • Increased pressure on North Vietnam to negotiate

US Locked In

General William C. Westmoreland, who seven months after Diem's assassination replaced General Paul Harkins as commander of MACV, summed up the consequences of President Kennedy's involvement. “In his zeal, the young president made a grievous mistake in assenting to the overthrow of South Vietnamese President Ngo Dinh Diem in 1963,” Westmoreland said. “In my view that action morally locked us in Vietnam. If it had not been for our involvement in the overthrow of President Diem, we could perhaps have gracefully withdrawn our support when South Vietnam's lack of unity and leadership became apparent.”

LBJ’s Dilemma

“In later years [Johnson] lamented:

Source

... But if I left that war and let the communists take over South Vietnam, then I would be seen as a coward and my nation would be seen as an appeaser, and we would both find it impossible to accomplish anything for anybody anywhere on the entire globe.’”

Joshua Zeitz"1964 - The Year the Sixties Began"American Heritage, October 2006

If I left the woman I really loved, the Great Society, in order to get involved in that bitch of a war on the other side of the world, I would lose everything at home. All my programs.

'I knew from the start that I was bound to be crucified either way I moved.

NVA: 12,000+ KIA (estimated)

Huge stocks of NVA weapons, ammo, food captured

US Domestic:Widespread protest in US, particularly on college campuses

Congress took first action to limit US involvement in SEA

• Cooper-Church Amendment

Page 76: Lessons 34 - 45 Review Slides

Congress and the WarUse of Budget to Restrict Operations in SEA

Cooper-Church Amendment (1970)• Sponsored by Sen. John Cooper (R-KY) & Sen. Frank Church (S-ID)

• Reaction to US-led invasion of Cambodia (April 1970)

• Prohibited use of US troops in Cambodia after June 30, 1970

• Approved by Senate 58-37 on June 30, 1970, after troops US withdrew

• House approved watered-down version December 1970

Significance:

First time Congress had restricted the deployment of US troops in wartime

Page 77: Lessons 34 - 45 Review Slides

Easter (Spring) OffensiveMarch 30 - October 22, 1972

ARVN performed reasonably well with US air support

DRV gained valuable space inside RVN for future offensives

Major conventional invasion on three fronts:• Across DMZ • Central Highlands

• West of Saigon

• Also gained bargaining chip in negotiations

Nixon began planning for Linebacker II

Nixon initiated Operation Linebacker• Bombing of North Vietnamese logistics targets

• Sustained bombing of North Vietnamese strategic targets

• Delay in starting due to need to return airpower to SEA

(May 9 - October 23, 1972)

Congress and the WarUse of Budget to Restrict Operations in SEA

Case-Church Amendment (1973)• After Paris Peace Accords (Jan 1973), Nixon hinted at US intervention if North Vietnam attacked South

• Introduced by Senators Clifford Case (R‐NJ) & Frank Church (D‐ID)

• Prohibited U.S. military activity in Vietnam, Laos and Cambodia after August 15, 1973 without Congressional approval.

• Passed by Senate 64-26, House 278-124 (June 1973)

Significance:

Essentially ended US military activity in Southeast Asia

Page 79: Lessons 34 - 45 Review Slides

US Evacuation of Saigon

Early plans had identified:• 8,000 US and third country citizens for evacuation• Number of potential South Vietnamese evacuees never determined

• • Estimate: 17,000 US employee + 6 family members = > ~120,000 evacuees

Late March 1975: Evacuations by commercial aircraft began• Last fixed-wing transport (C-130) left Tan San Nhut airport 29 April

• • Later estimates went as high as 200,000!

Contingency plans always existed for evacuation of US citizens• Also included “At risk” Vietnamese citizens

• • “At Risk” = US employees and agents

• The United States should not commit forces to combat overseas unless the particular engagement or occasion is deemed vital to our national interest or that of our allies . . . .

Weinberger Doctrine

• If we decide it is necessary to put combat troops into a given situation, we should do so wholeheartedly and with the clear intention of winning . . . .

• If we do decide to commit forces to combat overseas, we should have clearly defined political and military objectives . . . .

• The relationship between our objectives and the forces we have committed -- their size, composition, and disposition -- must be continually reassessed and adjusted if necessary . . . .

• Before the United States commits combat forces abroad, there must be some reasonable assurance we will have the support of the American people and their elected representatives in Congress . . . .

• The commitment of US forces to combat should be a last resort.
