No real President, though.
It’s not the US President’s call.
It’s the call of those who had citizens on the plane — the Netherlands, Australia, Malaysia, Britain, Indonesia ...
That’s why their Prime Ministers of those countries are taking the lead and sending troops to get their citizens back out of the grubby hands of the Russian-backed rebels.
The only US citizen on the plane was a dual citizen with the Netherlands.
For what reason would the US President try to insert American troops into the Ukraine? There were no US citizens on board that I am aware of. Nothing about this incident threatens US security interests. We have no business getting involved other than as part of the UN or lending moral support to the Europeans. They need to handle this one.
