We really should be behind our President, rather than driving him into the arms of the neo-cons with our protesting his actions.
Think of it this way. . As President Trump was hosting Chinese President Xi Jinping he had Xi Jinping on American soil and under American control when President Trump informed Jinping of the tomohawks' launches. During this luncheon at Trump's Florida home the tomohawks were falling on that Syrian airbase and President Trump made sure Jinping was aware of that while they were discussing possible remedies for North Korean belligerences, Sino-American relations and the South China Sea islands siezed by China.
One would think Jinping was rattled by Trump's unflinching demeanour while they dined as the missiles were raining down on Syria, (on empty hangers, but Jinping didn't know this at that time).
President Trump could not have picked a better way to send a clearer message of America's resolve for peace to President Jinping, than via 59 Tomohawks while dining on steak and sole!
