LATE LAST year the governments of the European Union, having refused to share the cost of a very successful operation called Mare Nostrum in which the Italian Navy rescued tens of thousands of refugees from sinking boats in the Mediterranean, replaced it with a much smaller operation called Operation Triton. Its purpose (though they didn't put it exactly that way) was NOT to rescue the refugees, because then they ended up in the European Union.
Triton was a "coastguard" operation, with a third of the budget of Mare Nostrum and orders only to patrol Italian and Maltese coastal waters. They could save any boatloads of refugees that made it that far, but they were not to do "search and rescue" operations off the Libyan coast, which is where most of the overloaded boats actually founder.
Inevitably, the death toll from drownings in the first five months of this year was 30 times higher than in the same period last year: at least 1750 human beings. The losses were so shocking that an emergency EU meeting in late April boosted Triton's budget back up to the level of Mare Nostrum - but they didn't change its "mission". It was still only supposed to operate in EU coastal waters.
But then something odd happened. Last weekend, ships from the Italian, British, German and Irish navies rescued more than 4000 people in two days - the vast majority of them just off the Libyan coast. The EU has not condemned the operation, but it wasn't really the EU's plan. What drove it was the sheer reluctance of the navies to stand by and let people drown.
The European politicians face a huge demand from their electorates to stop the seemingly endless flow of "migrants" (the preferred term for refugees, since it elicits less sympathy) across the Mediterranean. Last year 170,000 people made it across , and it could be double that number this year unless lots and lots of them drown.
