Fourth, what happens if a foreign threat we fail to address NOW shows up on our shores later?
This argument is absurd. There are very few nations capable of showing up on our shores with war intentions and Iran certainly isn't one of them.
Our stealth bombers can take off just a short distance from my home and bomb any place on earth just a handful of hours later. We have a deterrent and only need to be willing to actually use it.
The public show boating is unnecessary as the whole world knows what we are capable of.
