Iran is NOT clear and present or even impending danger to the security of the United States.
The clear and present danger is the dozens of EXISTING nukes in Pakistan falling in the hands of a jihadist regime.
You’re right about the dangers of Pakistan.
However, you are wrong about the dangers of Iran. The regime works thru proxies : Hezbollah, Hamas, alQaida, Taliban, etc. They have and will give aid to terrorist groups in order to carry out attacks against us in Iraq, Afghanistan, Lebanon, on planes, and elsewhere.
Not to mention that have and will attack our friends and allies.
