First of all, every president since at least 2001 has been a war criminal, and Biden is no different. So what I'm talking about is just the degree of war criminal.

That being said, let's look at recent policy changes, starting with Afghanistan.

United States troops and their NATO allies intend to be out of Afghanistan by early to mid-July, well ahead of President Biden’s Sept. 11 withdrawal deadline, military officials said, in what has turned into an accelerated ending to America’s longest war.

We are almost at a no return point. Granted, the Afghanistan army is already beginning to collapse, but after 20 years what would be different if we stayed another decade?
You can rightly point out that Trump wanted to get out of Afghanistan, but he failed to fight strongly for it. Yes, he signed a peace agreement with the Taliban, but he also dramatically increased the bombing of Afghanistan too.

Trump also wanted to end our illegal occupation of Syria, but failed to fight for it. Biden seems to want out too. What Trump wanted even more than pulling out of Syria was stealing their oil.

The Biden administration has decided it will not renew a waiver that allowed a politically connected U.S. oil company to operate in northeast Syria under President Donald Trump’s pledge to “keep the oil” produced in the region, according to a U.S. official familiar with the decision.

Treasury Department rules prohibit most U.S. companies from doing business in Syria. The waiver for Delta Crescent Energy was issued in April 2020, months after Trump announced that he wanted to keep some U.S. troops in the oil-rich region to maintain control of the oil profits.

Trump’s “keep the oil” message was no longer U.S. foreign policy under the Biden administration, and using the U.S. military to facilitate Syrian oil production was deemed inappropriate, according to the official, who was not authorized to publicly discuss the decision and spoke on condition of anonymity.

This is, of course, a very tiny improvement, but it is an improvement.

Finally, I want to bring up a very underappreciated policy change just a few days ago.

President Biden said that he lifted sanctions on the Russia-to-Germany pipeline Nord Stream 2 "because it’s almost completely finished."

"It’s not like I can allow Germany to do something or not," Biden continued.

"I’ve been opposed to Nord Stream from the beginning … they know how I feel," he said. Biden added that imposing sanctions now would be "counterproductive" since the project is almost completed.

So it's a policy change, not because it's the right thing to do, but because the anti-Russian coalition was defeated.
