The real threat of Iran is the combination of the willingness to supply and train terrorists while simultaneously seeking weapons of mass destruction. They have obviously demonstrated motive and means for delivery. What they have lacked historically is opportunity. We must continue to deny that opportunity.
A nuclear or biological weapon (such as weaponized smallpox from Kazakhstan) could easily be delivered with deniable culpability. Hence we simply must keep the Iranians from acquiring them, by force if necessary.
That's a case the American people will buy as long as they have proof that the Iranians are seeking those weapons (no brainer there) and intend to use them against America on American soil (which the attacks on our soldiers by Revolutionary Guards strongly indicates). The press release cites the latter without connecting it to the former. It gets a C in my book.
Duncan Hunter has been continuously talking about Iran for months. If you really want to see what he has been saying, let me know and I’ll start pinging you to the archives.
