It's laughable to say Iran is a threat to us, the only threat they pose is a threat to Israeli and Saudi hegemony over the region. Let them duke it out with Iran if they want, why risk American blood and treasure for their benefit? What happened to America first? I'm not interested in us being a b*tch to Saudi and Israeli interests.
Iran can send a freight there with a bomb or attack assets in Europe or the middle east as they do now.
Also, you may not realize Israel is an ALLY. That used to mean something when we had honor and determination. How even conservatives pee in their loans at the thought of stopping the worst supporter of terrorism in the world.
