A major geopolitical flashpoint has emerged as Russia and China vetoed a U.N. resolution aimed at reopening the Strait of Hormuz, effectively blocking U.S.-backed efforts led by Gulf allies like Bahrain. The proposed resolution would have authorised the use of “all means” to counter Iran’s blockade, but the veto underscores deep global divisions over the conflict. As tensions escalate ahead of Donald Trump’s deadline, Washington has intensified accusations against Tehran, further raising the stakes in an already volatile region.
