Iran is making a serious(and possibly fatal) mistake.
I wonder. Why now?
I mean, Iran has never gone to war against Israel. Not in the 1948 Israeli War of Independence, nor the 1967 Six-Day War, nor the 1973 Yom Kippur War.
Oh, sure. They make threats and sound tough, but they've never followed up.
Of course, if the world came to believe that Iran was going to attack Israel, then everyone would understand if Israel attacked them first.
