If Russia and I are unable to make a deal on stopping the bloodshed in Ukraine, and if I think it was Russia's fault - which it might not be - but if I think it was Russia's fault, I am going to put secondary tariffs on oil, on all oil coming out of Russia.

I still very much support Ukraine, but am convinced that massive escalation of the war will cause great harm to Ukraine and possibly the world.

When you are winning a war almost everything that happens can be claimed to be right and wise.

Many causes produce war. There are ancient hatreds, turbulent frontiers, the "legacy of old forgotten, far-off things, and battles long ago." There are new-born fanaticisms. Convictions on the part of certain peoples that they have become the unique depositories of ultimate truth and right.

War is not a polite recreation but the vilest thing in life, and we ought to understand that and not play at war.

If we assume that life is worth living and that man has a right to survive, then we must find an alternative to war.
