Unless the President is willing to back up his words with military aid, he's not serious about stopping Putin's armed aggression in the Ukraine.
The President should immediately issue an executive order approving the export of American natural gas to 20 countries that are awaiting bureaucratic approval. The highest priority should go to approving exports to Europe, where in many places, Russia has a near-monopoly on natural gas.
Furthermore, the President should issue an executive order approving 24 pending liquefied natural gas facilities that have been delayed by bureaucratic red tape.
This would be a serious blow to the Russian economy that would impose a real cost on Putin's foray into Ukraine. National emergencies justify actions that would not be taken in quiet times.
