Uh, the American armed forced withdrew from Vietnam, and a Democratic Congress cut off funding for the South Vietnamese Government. That's when the North overran Saigon and the US Embassy became a helipad.
The lesson here is not to repeat that mistake in Iraq by withdrawing troops and withdrawing support to the Iraqi government too quickly.
All true and our forces were withdrawn due to the antiwar people putting pressure on our elected officials and ultimately that Dem controlled Congress sealed the fate of the Vietnamese and Cambodians and Laotians in spite of Gerald Ford’s pleas to not cut off that funding.
The Rats can’t be allowed to repeat that again!
