Ever since our sages said 2,000 years ago that evil only befalls the world after the People of Israel suffer tragedy, there has been much proof to support their thesis. On Tuesday, there was more. Jews have always been the central and primary target for Islamic terrorism, but it has also always been clear that they are not the ultimate target. The Islamists are fighting Christianity. They want to conquer Europe as they did in the Golden Age. Were it not for the Jews, they would not have an effective excuse to launch a war of terrorism against democracy. There was an audience for slandering the Jews, and the current reason for this is apparently opposition to the occupation. As if it were the root of all evil. As if it were all the evilness itself. Clearly, they were throwing dust in people's eyes. You don't need to support a Jewish presence in Judea and Samaria to know that the region, and the Palestinians themselves, have nothing to do with global terrorism. From New York to Paris and now Brussels, there is a clear trend that is forcing the European Union -- which has been covering its eyes and ears -- to reexamine its conduct. Defending human rights at this moment requires limiting them for the purpose of saving lives. Europe is knee-deep in agreements that don't allow it to meaningfully track terrorists. It prevents itself from entering Islamic neighborhoods and from arresting suspects earlier than 5 a.m. There is no administrative detention or time-limited investigation. There is no guarantee that those who were murdered and injured in Brussels on Tuesday would not have been hurt otherwise. But one can say with certainty that they did not have the best protection that Belgian society could have provided for them had it taken the appropriate cautionary steps, or taken action -- as France promised to do, but did not quite follow through on -- to fight terrorism across the board. The world was shocked at the time. Even the Islamic State group thought it should prepare to take a hit. But the French president's words echoed in the speakers and through the headlines, and then it was as if nothing had happened at all. On Tuesday, I wondered in a tweet how long it would take for extreme leftist writers to return to claiming that "the occupation is to blame." Not that the occupation is good, it's damaging and onerous, but it is not the motive or the reason, nor will it ever be the source, for the spreading evil of radical Islam, which now has access to groups in Europe, some of which serve as the movement's vanguard. If Europe does not set out on a defensive war, it will find itself defeated in the evil war launched by its enemies.
