This week the world was horrified by the bombings in Brussels, which left dozens dead and hundreds injured. The attacks highlighted the seriousness and complexity of the threat facing both Europe and the U.S. Tough talk about refugees and closing borders isn’t going to do it. And yet Ted Cruz, just before turning his attention to fighting with Donald Trump about their wives, suggested we “empower law enforcement to patrol and secure Muslim neighborhoods before they become radicalized.” As if that’s not a recipe for radicalization. Meanwhile, Jeb Bush endorsed Cruz to “overcome” the “vulgarity Donald Trump has brought into the political arena.” But as low as the rhetoric on the Republican side has gone, what’s become standard policy dogma - indiscriminate bombing, deporting 12 million people, and revoking health insurance from millions more - is much more vulgar. The threats and challenges we face require real leaders, not pandering priapic preening and the same empty macho drivel that has led to so many of our present crises.
