It's long overdue to establish this:
Israel's military will set up a special branch in its general staff dedicated to threats from Iran, it said Tuesday. ...
Iran has forces based in Syria, Israel’s northern neighbor, and supports Hezbollah militants in Lebanon. In Gaza, it supplies Islamic Jihad with cash, weapons and training, and also supports Hamas, the Islamic militant group that rules the coastal territory. Israel also accuses Iran of trying to develop nuclear weapons — a charge Iran denies.
If Israel finally goes for the throat in a serious war against Iran's proxy Hezbollah in Lebanon, Iran will have other assets to fight back with outside of Lebanon.
So it is best not to think of Lebanon as an isolated front.
And of course this command will make Israel a more appealing ally to Arab states that want to resist and defeat Iran.
And America has a role in knitting those tentative co-belligerents against a common foe:
U.S. Secretary of State Mike Pompeo met with Saudi Arabia's King Salman on Thursday in a visit focused primarily on discussing shared security concerns about regional rival Iran.
Hopefully the loose coalition is strong enough to deter Iran from doing something spectacularly stupid and kinetic on the way to being defeated by the coalition.
It's always better to win without things and people blowing up around us.
