The last American soldier has left Afghanistan — though not the last American, as Joe Biden broke his word and left hundreds behind — signifying the end of a nearly 20-year military engagement. But this deadly debacle wasn’t how it should have ended, and America’s greatest enemies must have popped a celebratory cork because Biden’s weak and feckless leadership has served as an invitation to take advantage now.

Like clockwork, the United Nations’ International Atomic Energy Agency (IAEA) recently issued a report observing that North Korea has restarted its main nuclear reactor facility in Yongbyon. The plutonium production site had not been in operation since December 2018, following the historic meeting between Donald Trump and Kim Jong-un a few months prior. While the Trump administration was not able to secure a long-term denuclearization agreement with the rogue regime, it was able to apply significant pressure while making some geopolitical headway in the long, tense relationship.

It is significant that Biden’s Afghanistan defeat has motivated action by Pyongyang to essentially strike while the iron is hot. What better opportunity to press for sanctions relief than with a president who is so concerned with not breaking his agreement with terrorists that he’s willing to leave Americans behind?

Smelling this same feckless leadership, it should come as no surprise that the IAEA also reports that Iran has engaged in accelerating its own uranium-enrichment program. And the strategy is obvious: Pressure Biden to lift economic sanctions in exchange for a deal to supposedly delay nuclear weapons development. You know, kind of like the terrible deal Barack Obama “negotiated,” complete with pallets of cash.

The great irony here is that while Democrats and the Leftmedia warned of Donald Trump delegitimizing America’s leadership and in turn making the world more dangerous, the exact opposite occurred. Now, with Joe “C'mon, Man” Biden calling the shots, the world actually has become a much more dangerous place. Biden has delegitimized America’s leadership. Now America’s enemies see an opportunity to rapidly advance their nuclear weapons programs with little concern that Biden will do anything to stop them.
