Tomorrow Israeli Prime Minister Benjamin Netanyahu will address Congress, talking about the Iranian nuke situation.

This will be the third time Mr. Netanyahu has spoken to Congress.  The only other man to do that: Winston Churchill.

Now the Iranian deal is very complicated.

The Obama administration wants a settlement that would stop Iran from immediately developing a nuclear weapon.

But critics say the deal is too soft, that Iran would continue its weaponization and could convert it to nuclear very quickly if it decides to break the agreement.

Right now it's impossible to know just how close the Iranians are to having a nuke.

The Israelis believe they are very close and the state of Israel says that's unacceptable because the Iranian mullahs want to wipe Israel off the planet.

But President Obama has to negotiate on behalf of Americans, not Israelis.

And if the president walks away from the Iranian nuke deal, war might follow.

It's certainly possible so the stakes could not get any higher.

One of the problems with all the discord abroad is the perception of President Obama himself:

JASON RILEY, Wall Street Journal Columnist and FOX News Contributor: “This is a president who thinks America is the greatest threat to world stability.  And I think our allies and our enemies have picked up on this.  They see weakness, or they're concerned.  Assad sees weakness, Putin sees weakness, Netanyahu is concerned, so concerned that he is coming to this country because he feels that we're going to cut a deal with Iran that is going to jeopardize the very existence of Israel, an ally of ours.”

But again it's hard to know exactly what treaty terms would prevent Iran from going nuclear.

Therefore commentators like myself have to be careful.

Nobody wants World War III and nobody wants Iran to get a nuke, but definitive statements about the treaty negotiations are hard to back up.

On the other matter -- ISIS expansion -- it's easier.

Simply put, President Obama is not leading the fight -- King Abdullah of Jordan is.

KING ABDULLAH II OF JORDAN: “This has to be unified.  I've said this to leaders both in the Islamic and Arab world and to the world in general: This is a third World War by other means.  This brings Muslims, Christians, other religions together in this generational fight that all of us have to be in this together.”

But with all due respect to the king, who is a courageous man, it will take America to galvanize the world against ISIS and obviously that is not happening.

All in all, the danger overseas is growing no question.

And that's the memo.
