I never mentioned invade, but I did say American lives. Regardless, any kind of "kinetic action" draws us further into a military posture, and commits USA and Americans for many, many years to come. Thinking we can do this and then stand-down is too simplistic. Besides - who benefits? Do average Americans? NO.
Do Saudis and Israelis? YES!
Putting up with a bully comes with a price.
