Israel was placed in this dilemma last summer, when Iranian agents — the Hezbollah of Lebanon — crossed the border, killed some soldiers, and took two others hostage. Israel treated this aggression as a declaration of war, and its repeat in the Gulf waters has to be met with the same firmness. The making of any sort of deal whereby personnel legally arrested are exchanged for personnel illegally snatched — never mind anything that might compromise sanctions — would mean unconditional victory for Iran, and the admission of impotence and humiliation for Britain, and therefore the West.
