That is an incredibly simplistic view of the war in Laos and so wrong it isn't even worth correcting.
I see no debt owed to them by the US.
There is a debt owed by both sides. After the US unceremoniously left, the Hmong, among others, were the ones carrying on the fight against communism in SEA, not the US. They did have plenty of backing from the US government both officially and unofficially. The biggest supporters of the Hmong communities in the US are the former American Soldiers that fought next to them on the ground in Laos. Something to think about.
Of course given the choice of living in the jungle or a package deal to St. Paul from Lutheran Services we all know what they will choose.
They would much prefer going back to their villages up in the mountains in Laos and being able to live a free peaceful life. Unfortunately, they are not able to because of the government there.
