Has Donald Trump failed to sell the Iran war to the world?

Yet another day of US and Israeli strikes against Iran, and Washington says there's more to come, warning of a 'dramatic surge'. But with the exception of Israel, the US has NOT secured the active participation of any of its main allies, as was the case in previous conflicts like Iraq and Afghanistan. President Donald Trump hasn't hidden his frustration with European leaders, many of whom say the ongoing war is a breach of international law. That view is shared by other global players like China and Russia. But does it need them to continue to wage this war?
