Joe Biden gave a speech to Ukrainian legislators a few days ago. One statement really stood out to me:
And as you attempt to pursue energy security, there’s no reason why you cannot be energy secure. I mean there isn’t. It will take time. It takes some difficult decisions, but it’s collectively within your power and the power of Europe and the United States. And we stand ready to assist you in reaching that. Imagine where you’d be today if you were able to tell Russia: Keep your gas. It would be a very different world you’d be facing today. It’s within our power to alter that. It will take some time, but it’s within our power. Very difficult decisions, but within our power.One of those "difficult decisions" that is "within our power", would be to approve the Keystone XL pipeline.
