Bab al-Mandab is a narrow strait between Africa and the Arabian peninsula through which an estimated 12% of global trade by volume normally flows, and perhaps 30% of global container traffic. It has become a no-go zone as the Houthis, based in Yemen, attack shipping, ostensibly in support of the Palestinians in Gaza. Over a thousand miles from Gaza, a naval crisis is unfolding that could transform the war between Israel and Hamas into a global affair with implications for the world economy. Do you support Houthis actions in helping Palestinians in Gaza?
