North Korean dictator Kim Jong-un mailed a series of flattering letters to Trump between 2018 and 2019 which the latter described as "love letters."
Now, as it turns out, they were very lovely and border on the homoerotic.
Not that there's anything wrong with two men exchanging love letters, but these were exchanged between two heads of state and at least one of them knew exactly what he was doing when he verbally slobbered on Trump.
And for some reason, Trump allowed Bob Woodward to read and transcribe them.
This is just one example:
Your Excellency,
It has been 200 days since the historic DPRK-US summit in Singapore this past June, and the year is now almost coming to an end. Even now I cannot forget that moment of history when I firmly held Your Excellency's hand at that beautiful and sacred location as the whole world watched with great interest and hope to relive the honor of that day. As I mentioned at that time, I feel very honored to have established an excellent relationship with a person such as Your Excellency. [...]
I hope that Your Excellency will once again demonstrate great decisiveness and excellent leadership to accomplish results in the second DPRK summit. I wholeheartedly hope that the things that Your Excellency seeks to achieve will come to great fruition.
From these letters, Kim Jong-un ultimately got exactly what he needed and wanted from Trump if not more.
In exchange for this verbal blowjob, Kim Jong-un was legitimized on the world stage and North Korea's nuclear weapons program continued. Trump handed Kim an ever greater gift than he could have ever hoped for by declaring that North Korea had begun the process of disarming even if that wasn't really true at all. There was no reason for North Korea to follow through on anything if Trump was already declaring the matter settled.
North Korea will likely test the Biden administration within the first year if not the first few months and the latter will have fewer ways to respond because of Trump.
