Iranian Official - 'We Will Use Our Missiles to Protect Other Muslim States'

The fear of a nuclear Iran is not that they will use them rationally to defend themselves. The fear is that they will actually use them (or give them to someone else to use) or use the threat as a shield to act even more belligerently while giving a free pass to their belligerent 'buddies'. Belligerence here is code for terrorism, in case you did not follow.

"Last Thursday, Iranian Parliament Speaker Ali Larijani — while at the Syarif Hidayatullah State Islamic University in Indonesia — stated that Iran will use its missiles to defend other Muslim nations if threatened.

This is the first time that a high-ranking Iranian official has issued such a warning. In effect, Iran is expanding its defense strategy from protecting their own sovereignty to a “defensive umbrella” over other Islamic nations.

Larijani based his argument on what he called “the school of the late Ayatollah Khomeini,” the founder of the Islamic Republic: Muslims should possess enough defensive strength to use against other countries should one of those countries attack."
