Donald J. Trump is having a busy week, indeed.

The president has taken direct aim at (a) the Affordable Care Act, (b) the Iran nuclear deal and (c) the United Nations. To what end? To show the world he’s putting “America first” and that he doesn’t care what the rest of the nation that didn’t vote for him thinks about the policies he is dismantling.

* Trump this week declared his intention to discontinue the subsidies the government pays to reduce health insurance premiums for Americans who need them to purchase insurance under the ACA. He’s seeking to destroy former President Barack Obama’s signature legislative achievement, no matter how many millions of Americans he hurts along the way.

* The president has decided against recertifying the Iran nuclear pact that Obama’s foreign policy team negotiated with five other nations. It seeks to demand that Iran quit developing nuclear weapons. International analysts say Iran is complying with the deal; Trump says the Iranians aren’t complying. Hmm. Who do you believe, the experts or a pathological liar?

* Trump has decided to pull the United States out of UNESCO, a UN-affiliated organization dedicated to developing world peace through collaborative educational, scientific and cultural reforms. That sound pretty nefarious, right? He cites an alleged “anti-Israel bias” in the UN. So, he’ll just pull us out of UNESCO. That’ll teach ’em.

The president just cannot stop doing things that make many of us angry. Sure, he pleases a lot of folks around the country with this so-called “no-nonsense” approach to domestic and international policy.

In my own view, though, he is forsaking policies only because they were crafted by his predecessor, the fellow Trump defamed by suggesting for years he wasn’t qualified constitutionally to serve as president; it’s that “birther” thing.

As for the UNESCO pullout, Trump is managing to anger allied nations who do not view the world through the same distorted prism the president uses.

But, by golly, he’s telling it like it is.
