It hurts how dumb you are.
Non-WMD Precision guided missiles are the main tool for power projection for every global power. That's why the U.S has them, and every strong country in the world (China, Russian, Pakistan, India, UK, France, Italy etc..) stocks hundreds even thousands of them on huge fleets of warships, or jets, or land to strike static targets from far distances. In any attack, a strong country armed with precision guided missiles would fire 100's in an overwhelming barrage to strategic targets all around a country, to paralyze a country from safe distances. See Nato first strike on Iraq (Nato destroyed most of Iraq's air-force on the ground), on Syria, on Libya from both sea and air. The ability to do this is what 90% of nations dream about. Iranian strike on Kurdish terrorists is just an example of what Iran can do with precision guided missiles, but on a small scale. Those missiles are smaller because they are of shorter range than scud missiles. If you fail to understand any of this, I can't help you from embarrassing yourself.
But naturally, you go on a rant about how one us nuclear missile can wipe out Tehran as if that proves anything about the value of missiles. Thanks for the useless information...
Also, 50-100 Ballistics missiles is well within Iran's capability, and arming them with chemical weapons should not be an issue for Iranian scientists as well if Iran is forced to use WMD's.
