It's what you mean. Overthrow Erdogan? Yeah, regime change. An invasion with destination: Ankara.

Crushing one country after another because we regard them as a "threat" has, as its inevitable outcome, a world where all countries are one. Imagine what the game of Risk looks like when someone wins. Armies on all territories, all opponents eliminated.

Maybe you don't realize what you're saying, but I do. Regime change is what we did in Iraq. Conquering and destroying are accurate words, no matter how much you don't like them.
