To be entirely honest, I think having the US here is far more dangerous for us than Russia:

1. War on European soil will hurt Russians and Europeans alike. Both physically and economically.

I grew up during the cold war and was deeply thankful to Mikhail Gorbachev for ending it peacefully. Now I could travel freely to Praag, Wachau. Berlin was whole again. Work with Poles and Lithuanians, etc. That was utterly amazing and deeply mentally and physically liberating. Hard to explain in words. I do not want my child to grow up under a new cold war. Hence I must speak up now. Clearly. For her and all other children here in Europe.

2. Size matters. The US is sending 54 billion dollars worth of weaponry into Europe. To fight any enemy with an economy the size of Spain. All weapons are meant to deliver death and destruction. That's exactly what they will do. Right here, right now. So yes, I should be very worried as we all know that conflicts always spread into the regions nearby. Meaning us. The chances of a proliferated US weapon killing my child are not imaginary.

3. Biden is very clear about his aim: to destroy Russia. Never force a cat in a corner and expect to come out unscathed. Even a "regional" nuclear war will affect the US badly. Don't be fooled you're safe. Let's rather be safe than sorry. Putin and Biden will be gone one day, let's work towards that life on this planet then still can continue.

4. Why is the US so very interested in Ukraine...... (and why was Biden's son already in Ukraine, well before the war?).....well that too is clear for anyone who has been following geopolitics for some time. ..

Just google for yourself "George Kennan's U.S. containment policy" and see how it evolved from idealogical to economical, the Bush-Cheney's naked exploitation and total destruction of Iraq. Are we next????

Wouldn't you worry and rather fight for peace and aim for prosperity?
