How national security is being redefined by climate change

One of the most unfortunate fault lines in climate change politics today is the lack of cooperation between environmentalists and the national security community. Left-wing climate activists don’t exactly hang out with more right-leaning military strategists, the former often seeing the latter as destructive anti-ecological marauders, while the latter often assume the former are unrealistic […]

Social platforms wrestle with what to do about the Taliban

With the hasty U.S. military withdrawal from Afghanistan underway after two decades occupying the country, social media platforms have a complex new set of policy decisions to make.

‘Star Wars’ returns: Trump calls for space-based missile defense

The President has announced that the Defense Department will pursue a space-based missile defense system reminiscent of the one proposed by Reagan in 1983.
