It's a virtual certainty at this point that our President is going to use nuclear weapons on someone – Does it matter who? – just to do it.
Having already prevailed upon the Pentagon to drop "the biggest bomb you have" on a rural area in a country that is essentially medieval, it's clear that he believes that this "sends a message." He's not entirely wrong. It sends the message "I am completely insane," after all.
Aside from its obvious saber-rattling and dick-waving value, using nuclear weapons appeals to his belief that doing something that no one else would do is a sign of bold leadership. Add in the fact that it will send all the right people into fits of apoplexy – the U.N., Europe, liberals, the media, people who read books – and it becomes more a question of when rather than if.
Recognizing that there is virtually nothing of value to bomb in Afghanistan – we've heard the bullshit about "underground tunnel complexes" that turned out to be fantasy before, remember – North Korea seems like the more likely target. Or who knows, maybe he'll blow one up at random just to make himself feel tough.
It isn't hard to picture him yelling about "a real big bomb, the biggest one!" because we have seen that this is his entire worldview in a nutshell; things that are real big are better than things that are not, and the biggest thing is definitely the best thing because it's big. In short, he thinks like a 10 year old boy. We've known that for a long time. What is beginning to sink in is exactly what the consequences of that mindset are going to look like. Remember all that talk during the election about making sure that an unhinged egomaniac didn't get his finger on the nuclear trigger? That wasn't idle talk, it turns out.
