Keep in mind, wrt Trump and conquest, he thinks we (the US) should break international law and claim oil (and other resources) from the countries that we've already invaded. And he still wants to take the war to ISIS. Even if it's not a war of conquest, it's still a war outside our borders and a major talking point of his campaign and his disparagement of Clinton and the Democratic Party (their apparent refusal to reference ISIS in particular and Islamic terrorism in general).
