Why blame outside powers again? There are very large differences where you have very limited differences in outside power rule, a big example being India vs Pakistan. And this is very far from the only example.

There have always been and always will be outside powers. Hell, the very first stories we have, from the Epic of Gilgamesj, the oldest stories in the Bible and Greek Legends are all about outside powers intervening, and here we are, over 4000 years later, and there's (checks wikipedia) 32 current wars (and none are "the west" doing that at the moment, China is currently the worst offender, there's of course Russia and Ukraine/Europe) where outside powers are trying to dominate someone else. At some point you have to accept outside powers trying to fuck things up as a basic part of life. So other countries will keep intervening, probably for another 4000+ years.

What do you mean by "war", exactly? The US bombing Somalia, Colombia and Venezuela clearly does not count, and neither does the SOF:s in Syria and Iraq, or the proxy wars in Ukraine, Yemen, Palestine and Lebanon. I suppose the trade wars don't count either.
