In reaction to a gas attack that killed scores of people in the Syrian rebel-held province of Idlib, President Trump released a statement blaming former president Barack Obama for the incident, specifically for doing “nothing” against Bashar al-Assad’s regime even after it used chemical weapons.

Trump, of course, has talked about the Syrian regime as a potential ally and adamantly opposed U.S. intervention in the conflict:

President Obama’s weakness and indecision may have saved us from doing a horrible and very costly (in more ways than money) attack on Syria! — Donald J. Trump (@realDonaldTrump) September 1, 2013

AGAIN, TO OUR VERY FOOLISH LEADER, DO NOT ATTACK SYRIA – IF YOU DO MANY VERY BAD THINGS WILL HAPPEN & FROM THAT FIGHT THE U.S. GETS NOTHING! — Donald J. Trump (@realDonaldTrump) September 5, 2013

That’s not all.

Trump, who has played golf nearly every week since his inauguration, also attacked Obama for golfing while countries in the Middle East “burn”:

He suggested that Obama could bring down the Syrian government by giving them universal health care:

If Syria was forced to use Obamacare they would self-destruct without a shot being fired. Obama should sell them that idea! — Donald J. Trump (@realDonaldTrump) September 6, 2013

And also suggested that while Obama weighed his options regarding Syria, he should carry out a sneak attack on Iran instead:

While everyone is waiting and prepared for us to attack Syria, maybe we should knock the hell out of Iran and their nuclear capabilities? — Donald J. Trump (@realDonaldTrump) September 5, 2013

Another suggestion: If we go into Syria, take the oil!

We should have gotten more of the oil in Syria, and we should have gotten more of the oil in Iraq. Dumb leaders. — Donald J. Trump (@realDonaldTrump) March 16, 2012

Trump also pushed the false claim that the Obama administration was arming ISIS:

So Obama wants to bomb ISIS in Iraq & arm them in Syria? What is he doing! — Donald J. Trump (@realDonaldTrump) September 17, 2014

But here’s an idea that, now that he is president, Trump did not take to heart.
