Even a temporary closure or military disruption in the waterway would cause energy prices to soar and could politically destabilize the Persian Gulf region. Far less attention has been paid to Iranian activity in the Red Sea, however, despite the crucial importance of the Bab-el-Mandeb Strait to world oil shipments.
