Hi Gary - Biden has taken harsh action against Putin, but Putin doesn't much care for the opinions of the international community. Nor will he be disuaded by economic sanctions. He will continue until he is stopped, and stopping him will likely entail force. But Europe cannot sit back and wait for us to stop him. In my view, we need to come to a consensus on how to do so, jointly, as Gazz noted, with Germany and France (and the British Commonwealth). The Visegard countries, the Baltics, Romania and Bulgaria will readily follow, but the rich powerful countries need to lead.
As to the bombing, I think Russia has been very restrained if you look at their history. They usually like to indiscriminantly bomb before moving in troops, which they have not done in Ukraine. They remain rather casual about measures to avoid killing civilians, but so far, their approach is not as brutal as your typical Russian military advance.
