The recent assassination of Iran's leading nuclear physicist has violently stirred up ye olde hornet's nest. Please see the link for the article from JPost. You can almost feel the simmering anger of the Iranian regime. They are FUMING. And, of course, they put the full blame on Israel.
Added to the words in the article are suggestions (by the Iranians) that the USA may start a firefight before Pres. Trump leaves office. Reading between the lines - the Iranians may just place themselves on the offensive. Initiating a strike, rather than being caught on the defensive.
The rhetoric is ramping up by leaps and bounds. I sense panic in the air.
