The fact that we have been engaging in never-ending wars having no clear plan on what victory looks like is spot on. Biden boasts about leaving Afghanistan (a totally screwed up withdrawal at that), but now gets us involved in a proxy war with Russia? There is no rationale where that makes any sense. Out of the frying pan and into the fire.
Looking at the situation you described from an American Republic perspective, the foreign policy actions taken since WWII does not make any sense.
However, if you analyze the same situation from a perspective of America being an empire, those same actions make total sense.
Did Kuwait teach us nothing?
The first US-Iraq War only taught the Power Okole that runs the US empire that their once vassal puppet Saddam Hussein needs to go since he would no longer do their bidding as he did in the past.
We've tried for over a century to project our power onto others so they will be friends.
There is something obscenely wrong with that statement. Since when did power projection earn the friendship with other nations?
Looking back into World history, power projection among nations has almost always been used to intimidate or force other nations into compliance with the geopolitical goals of that nation that is doing the power projection.
So far, most of those friends have rarely returned that favor.
Why should any nation submit to the overt/covert threats and/or provacations (i.e., power projection) made by another nation?
