Prime Minister Mark Carney’s much criticized ambiguity about the role of international law regarding U.S. and Israeli attacks on Iran is more than an excusable stumble by an inexperienced politician operating in a challenging environment.

Carney is building a foreign policy “doctrine” that increasingly warrants a closer look.

Last October, Carney lavished praise on U.S. President Donald Trump for supposedly “disabling Iran as a force of terror” with U.S. strikes months earlier. While the prime minister has softened — but not withdrawn — his support for the current military campaign that began in spite of progress on peace talks, he has not explained why he has long disagreed with intelligence assessments that Iran was not pursuing a nuclear weapon.

Nor has Carney or his ministers refused to rule out some form of participation in the conflict that is rapidly extending to other Persian Gulf states.

An opportunity to provide clarity on such issues was rebuffed when Carney skipped an emergency debate in Parliament on the growing crisis. Meanwhile, the war continues to unleash enormous human suffering and chaos.
