We have some precedents in our own history, especially in the beginning of the WW II, and a lot of people are shaking their heads - we consider ourselves as important US allies but it's clearly interpreted as the sign that you can only count on yourself in this world.
I remember hearing that on the news regularly since at least the invasion of Iraq, and I still don't understand why our politicians keep repeating it. It's bullshit. To the US, we barely register on the map.
In fact, the reputation of those latter arms of our government is so deep in the dumpster at this point that I cannot believe anyone who becomes entangled with them can claim naivety.
This idea that the USA has a deep obligation to a handful of communist ethnic militias in the Middle East is an intel psyop, and you're falling for it.
