It's not safe

[T]he State Department has urged all Americans to depart not only Iraq but also Pakistan, Bahrain and the United Arab Emirates.

That's funny. Pompeo - the very head of that department - said Americans are safer now that we assassinated Soleimani: “The world is a much safer place today. I can assure you that Americans in the region are much safer.”

Americans nowhere are "much safer."  In fact, they are at much greater risk.

United States military, diplomatic and commercial operations as well as civilian targets throughout the Middle East are in range of both Iranian missiles and terrorist cells. From Afghanistan and Europe to Africa and Latin America, Iranian proxies — once latent — can stage asymmetric attacks against American and allied targets without warning. Even in the United States, we have reason to fear that terrorist sleeper cells could be activated. Worse, we face these threats now substantially alone, as the Trump administration apparently neglected to consult or even warn our key allies and partners about the impending risks to their interests that result from killing General Suleimani.

In Iraq, Iranian-backed militias have attacked United States and allied installations, and can continue to do so around the country. The government in Baghdad has declared the killing a violation of the terms of the American military presence in Iraq. We will face mounting pressure to withdraw our military and diplomatic personnel from the country. If we leave, the United States will suffer a major strategic defeat: Iran will justifiably claim victory, and the gains of the fight against ISIS will be lost as the terrorist group rebuilds.

There is no hope now to revive, much less strengthen, the Iran nuclear deal, and we must expect Iran will accelerate its efforts to revive its nuclear program without constraint.

The global economy is imperiled, as the Gulf States’ energy infrastructure faces the risk of an Iranian attack, and commercial shipping through the Strait of Hormuz and the larger Gulf region is threatened.

Well done, Trump cabal.
