As a veteran, and as a governor who has supported Texas National Guard deployments to Iraq and Afghanistan, I can understand the emotions behind isolationism. Many people are tired of war, and the urge to pull back is a natural, human reaction. Unfortunately, we live in a world where isolationist policies would only endanger our national security even further.
That’s why it’s disheartening to hear fellow Republicans, such as Sen. Rand Paul (Ky.), suggest that our nation should ignore what’s happening in Iraq. The main problem with this argument is that it means ignoring the profound threat that the group now calling itself the Islamic State poses to the United States and the world.
