You are wrong. It's a war. Moreover it's a war for survival. It's not a war against Putin or his government, it's the war against Russian people. The aims of the war range from provoking a forced change of the power in Russia as it was earlier made in Ukraine to disintegrating Russia into several unfriendly states leading permanent brother-killing wars against each other. The thousands of innocent victims in the South-East of Ukraine as well as the hundreds of the passengers of the Malaysian Boeing have already become the victims of this war.
On the other hand, the Ukrainian bomb is meant to undermine not only Russia, but Europe as well. So, it's very naive to hope to stay untouched by the war. The bell tolls for everyone, as I used to say earlier.
As we cannot dodge from participating in this war, we have to take the sides. For Russians there is little choice since we are cornered. We will strike back.
As for Europeans there is a choice - either to follow the US politics and to lose their political and economical sovereignty or to take their own side and ally with Russia.
