Can any christians explain this to me?

I am not a christian but i have read alot regarding a prophecy from the bible, that says all Arab nations will band together and attack Israel..Iran will be the leader of this war.. Surely no one is damn silly enough to start a war with Israel, as America will side with Israel and it will surely cause world war 3.. Although iran make tons of threats against Israel, are they really stupid enough to carry out these threats..The countries that will be involved are listed as 10 nations from the east which will be syria, lebannon, turkey, iran, russia, china, iraq, Afghanistan and two others,,
