The political TV advertisement featuring Binyamin Netanyahu and the slogan “The world needs American strength, not apologies” is likely to fuel claims that the Israeli prime minister is interfering in the US presidential election in support of Republican candidate Mitt Romney.

It comes increasing during anxiety that Netanyahu has overplayed his hand in displays of warmth and enthusiasm for Romney while his relationship with Barack Obama grows more antagonistic. Some say Netanyahu is gambling too heavily on a Romney victory on November 6 and that if Obama is re-elected, the potential blowback could be damaging not just for the prime minister but for Israel itself.
