They should be ejected immediately.
Would you rather have them as an ally or fight them? Turkey is not less than the third strongest military power in NATO.

Israel is not a concern of NATO. If Israel tries to (1) exterminate the Gaza population, or (2) expel them from the land, or (3) to simply take all of Gaza, then Turkey or another Muslim nation may get involved. Until recently, it seemed #2 was not possible because nobody would take the Palestinians, but the unlikely candidate seems to be the United States.
Turkey is threatening action against Israel. As a NATO “ally”, we’d be obligated to help Turkey if Israel were to (rightly) retaliate. I don’t want to be in a situation where that is happening... that’s why I don’t like to hear that kind of scimitar-rattling.
