A few points and lessons come out of yesterday's historic events in Northern Ireland.
Firstly, and sadly, this shows that terrorism works. Now that the Troubles are over, Catholics are in a completely unimaginable position in sharing leadership compared to where they were before. Violence, despite the elevation of the peaceful figures who took the plaudits in the end, was pivotal in South Africa and India before for example. People like Mandela (who previously himself engaged in violence) and Gandhi would have been nothing if there was not the violence to compare the peaceful process with. This is not the lesson though. If anything has to be learned, is that we need to get rid of injustice before it gets to the level where violence begins.
Secondly, to achieve peace, you need to sit down with people who you don't agree with. Astonishingly, people are reporting that there is "chemistry" between Ian Paisley and Martin McGuinness. These men loathed each other, and "moderates" in the centre loathed both. But without them on board, there would be no peace.
Thirdly, peace can be achieved despite parties not agreeing on everything. Sinn Fein have not dropped their dream of a united Ireland. But peace there is, and all sides expect it to stay. Comparing this to the situation between Israel and Palestine, preconditions on longterm visions have to be dropped. The proposal of withdrawing to 1967 borders for a longstanding peace is a sensible one. If either side still hanker over one-state, then they should be allowed to do so as long as it is only done by the force of argument, and not trampling on the rights of others.
