All of these people going to Ukraine to fight are idiots. Russia is a huge country. Russian pipeline extends down into Europe. Russian ships & shipping ports all over the coasts. If you want to bloody Putin's nose, you take the fight to them. It would be much easier for Ukrainians who could much more easily pass for Russians. Take out one of their oligarchs and minds might begin to change in Russia. Disable a railway line. Take out a pipeline. Sink a ship.
