The Wall Street Journal is reporting the US is scrambling at least two warships to protect Israel and American forces in the region. An attack from Iran in retaliation for Israel’s attack on a diplomatic building could occur anytime.

Iran’s supreme leader, Ayatollah Ali Khamenei, publicly threatened retaliation for the Damascus strike and Israel disrupted local GPS networks that can be used to guide weapons.

US officials fear that an Iranian strike against Israel could prompt an Israeli response inside Iran that may spark a regional conflict and draw in America, whose forces and allies in the Middle East could be targeted by Tehran.

John Kirby, the White House’s national security spokesman, said Iran’s threats to strike Israel remain “real” and “viable.”
