Realities get murky when you talk geo-politics. Some times it's in the interest of the US, to protect the self-determination of a nation, especially when it goes against the interests of a geo-political adversary. We see this with your country, Ukraine, Latvia, Lithuania, Estonia, etc.
At other times, it means selling F-16s, Apaches and munitions to Saudi Arabia, so they can carry out a brutal bombing campaign in Yemen. There are no good or evil regional powers, only national interests and the smaller nations which either get in the way of those, or help you achieve them.
