Scowcroft on Ru: "we assume we have to match them w belligerence." Let's show some creativity in our response
To date the options exercised seem half-hearted and without any clear explanation to the public here. The sanctions against individuals are pathetic, yes they signal opposition, but are nothing more than a public display.

Military options have their place, although deploying into the Ukraine now is un-wise. It must be a common NATO display and I've yet to see any such reporting.

Wider economic sanctions need to be creative, although some of Carl's options would be stark signs of "no more, the cost can get higher".
