I really see no reason to go into Iran.
Their missiles are pathetic. They have not yet tested a nuke. And the world is going to whine if we act against them. I say screw it, and let Iran's next door neighbors deal with it.
Call us when their missiles have a range of 7000 miles.
"And the world is going to whine if we act against them."
The world is going to whine regardless of what we do or don't do...nuke 9-10 of their largest cities and all of their nuclear sites...problem solved...move on.
Here's a "missle" that usually has a range of about 14,000 miles.
I'm sure Iran has thousands of these.
Problem is when Iran nukes us, we won't be able to trace it back to them.
"Call us when their missiles have a range of 7000 miles."
Then it would be too late. Iran isn't like the old Soviet Union. They wouldn't hesitate.
