I’ve looked into that. A majority of Iraqi subjects (I’ve seen 80%) did in fact welcome the US as liberators. But the ones we liberated them from… saw things differently.
You can’t free the oppressed from their oppressors without angering and upsetting the oppressors in the process. I say don’t fight other peoples’ fights for them. Why make their enemies our enemies? But if a regime is creating trouble for us, then… yeah. Topple the bastards.
And it really doesn’t matter whether we’re seen as liberators or not.
I predict the majority of starving peasants in North Korea will welcome an invasion. I also predict they won’t be the ones whose point of view matters, because they’re not the ones with the guns and missiles.
It’s going to be a tough fight, but not half as tough as the consequences of not fighting would be.
