Take the Pirates back to your country for trial
I don't think that this is a good idea, well not in the UK, or Canada for that matter. If you bring them back they would get legal aid to fight the charge. Some are likely to evade justice through fancy lawyers and then end up claiming asylum, with no way of being deported to a war-torn country where their lives would be in danger (bless them)! The next thing you know, the whole extended family will be living on an estate in Bristol (UK)...............hang on, that has already happened!
Can’t we put an exclusion zone off the coast of Somalia and sink anything that is approaching it? It worked in 82.
