The humor derives from the fact that the past three presidents all ran for office committed to reducing America's interventionism overseas but once in office they reversed course and expanded US military commitments worldwide, turning them into facsimiles of John McCain, who has never seen a war he didn't like.

President Donald Trump's explicit pledges to avoid expanded engagement in Asia and the Middle East while also fixing the relationship with Russia are by now lost down the memory hole as he has increased troop levels in Afghanistan while, by his own admission, the relationship with Moscow is now even worse than it was during the Cold War. And regarding Syria, his Ambassador to the United Nations Nikki Halley has confirmed that the US military will not be going anywhere because certain goals have to be met first. One objective, monitoring developments relating to Iran, is open-ended, implying that it will be impossible to leave for the foreseeable future and suggesting that another Afghanistan-style quagmire is in the making.
