Perhaps you’re of the opinion that Ukrainian refugees aren’t our problem, that the world has always been full of foreigners doing ghastly things to each-other, and we can’t be expected to change the settled migration policy of our country just because of a war. Perhaps you wonder why, if we’ve been talking about using gunboats to repel boatloads of Libyans or Syrians and were forced to be ‘realistic’ about the number of people we could accept from Afghanistan, we’re now getting sentimental about Ukrainians.
