USA did nothing concretly to support Khmer Rouge after Vietnam war, only China did with weapon and military advisers. in fact, in cold war China is trapped by US when China PRC thought that US will let China to be boss of region.
Talking about Indo-China ambitous of Vietnam is cheap propaganda of PRC.
Yes, that is true. The United States doesn't really have the best intelligence gathering network , as recent events have shown in this epoch. So the same reality is true in regards to American interaction with Cambodia during this time frame of the post-American evacuation of Southern Vietnam.
well said. plus, with the Khmer Kingdom becoming weaker and weaker, Cambodia is unable to stop both Vietnam and Thailand as the duo sought hegemony on indochinese mainland. it is understandable the khmer seek help from China. cambodia and laos were in danger being slowing swallowed by Vietnam and Thailand.
In fact, my friend, Cambodia was indeed "swallowed" by both the Vietnamese Empire and the Siamese Empires on various times in history. The Siamese King Taksin the Great (the ruler who saved Siam from the Burmese) actually punished the Khmer King Anuvong after he liberated Siam because during the years when Siam was being subjugated by the Burmese Tongoo, the Khmers cooperated with the Burmese to seize eastern Siamese territories that were given in return by the Burmese for "helping" subjugate the Great Siamese Empire.
When King Taksin I rose to the throne of Siam, after he defeated the Burmese near what is now Louang Prabang , he then sent his army to Lovek (then capital of Kampuchea / Cambodia) and he sacked it. Burned it to the ground and enslaved the whole population , brought them back to what is now Ayudhaya.
The same thing with the Vietnamese Emperor Gia Long took the throne, he then led a campaign to defeat the Siamese near what is now Battambang and made eastern Cambodia a Vietnamese "sattelite" state. A tributary state, if you may.
