The London Terror Attacks May Mean More Votes for Theresa May's Conservative Party").
However, if they are right, then that raises a interesting question: Why do terrorists carry out such attacks if they help political parties that are more likely to oppose them coercive? It isn't because they don't know what they're doing. As I've pointed out previously, terrorists are not stupid and, in fact, are often quite well educated ("Terrorists Aren't Stupid (Nor Are They Ignorant)"). Thus, it's likely that they carry them out because they believe it's to their benefit to do so.
But what benefit might they derive from such attacks? I'd argue that it triggers political reactions that leaves the impression that those of us living in the West do not like Muslims, that we are hostile to the Islamic way of life. For instance, ISIS has reportedly referred to President Trump's proposed travel ban as the "blessed ban," not because it helps the world's Muslims, but because it helps to reinforce the belief that Muslims are not welcome in the West.
What can we do? Well, we need to work hard to counteract such an impression, whether we do so through ecumenical events at our own faith communities or by paying friendly visits to local Islamic mosques. I confess, however, our task is quite difficult when so many of our politicians seem more interested in inciting animosity toward Muslims than they are in welcoming them as full and faithful members of the democratic West.
