What did Donald Trump do today?

He agreed to another summit with Vladimir Putin, possibly because of a hallucination.

Two months ago, Trump hosted Russian autocrat Vladimir Putin at a summit meeting in Alaska. That meeting that was widely regarded as an embarrassment at the time, and it only got worse in the ensuing months as Putin continued to stonewall Trump's pleas for a politically useful ceasefire in Ukraine, while escalating his aggression against NATO members. 

Trump has never shown any real ability to stand up to Putin, who actively interfered in American elections on Trump's behalf, and who exercises power in Russia in a way that Trump has at times been openly envious of. But he has been attempting to cajole other nations to stand up to Putin on his behalf, by threatening them with trade sanctions if they continue to buy Russian oil and natural gas.

Today, Trump announced that he had agreed to meet Putin again, this time in Hungary. The reason he gave was that he believed he'd made "great progress" in a phone call with Putin today.

The problem with Trump's optimism is that he also apparently believes that he had a good phone call with Indian Prime Minster Narendra Modi yesterday, one in which Modi promised to stop buying Russian oil. But the Indian government has confirmed that no such phone call took place, and that there was no such agreement in place.

The silver lining is that all indications are that Trump really did talk to Putin today, and that he is not imagining it. But Trump is famously secretive about his communications with Putin: he once sought to have a special private communications channel put in place that his own government couldn't monitor, and he's been paranoid about U.S. government translators knowing what he's saying to Putin, so much so that he's confiscated their notes or done without them entirely. As such there's no way of knowing what was actually said or why Trump suddenly feels so optimistic.

That is, unless Russia once again decides to embarrass Trump by sharing with the American public details of Trump-Putin diplomacy that Trump was trying to hide from them.

Why does this matter?

• A president who is having hallucinations or is otherwise profoundly confused about what is happening around him is not fit for office. 

• Trump is hopelessly compromised by the Putin regime even if he's fully coherent and alert.
