Donald Trump, like most Americans, like most Republicans, believe in protecting America's core national interests. He believes as do I, as do most Americans, that we aren't yet doing enough to take the fight to the Islamic State.That the intervention in Libya was ill-considered and slapdash at the time.

In military terms, if you're not winning, sometimes you are losing. We've seen the Taliban and associated terrorist organizations make gains in recent years. It's time to stop those gains and roll them back. There's a lot of different techniques to do so, but we cannot allow Afghanistan to once again become an ungoverned country from which terrorist organizations can launch attacks against the United States and our citizens.
