Cambodia and Laos were not parties to the war, so bombing them was illegal. That's why Nixon did it in secret.
The notion that 'Democrats" sold out the South Vietnamese regime is also bullshit. We continued to fund them all the way up to the day Saigon fell.
Since partisans have turned the April 30, 1975, Communist takeover of South Vietnam into a political weapon, I’m going to spend the anniversary doing a little myth-busting.

Mel Laird, Richard Nixon’s defense secretary, started the modern myth that “Congress snatched defeat from the jaws of victory by cutting off funding for our ally in 1975” in a 2005
article in Foreign Affairs, the journal of the prestigious Council on Foreign Relations.
It wasn't true, but that never stopped a meme.
$700 Million
A quick, easy check of an old newspaper database shows Laird's cutoff claim to be
false. In the fiscal year running from July 1, 1974, to June 30, 1975, the congressional appropriation for military aid to South Vietnam was $700 million.
The
Times reported that with National Security Adviser and Secretary of State Henry "Kissinger's personal prestige tied to peace in Vietnam, his aides have said that he will try to pin the blame for failure there on Congress." He tried to do just that at a March 26, 1975
news conference in which he framed the question facing Congress as "whether it will deliberately destroy an ally by withholding aid from it in its moment of extremity." Three years earlier, in October 1972, the month in which Kissinger publicly proclaimed that "peace is at hand," he privately told the President that their own settlement terms would destroy South Vietnam.
Congressional aid cuts didn't determine the war's final outcome. Saigon's fate was sealed long before, when Nixon forced it accept his settlement terms in January 1973.
As for Laird's "cut off" of funds for Saigon, it just never happened. Even Nixon acknowledged the 1975 military appropriation for Saigon of $700 million (on page 193 of No More Vietnams).
