Actually with him it's "Give me Greenland and Cuba is next"

That’s not fair, he’s promising to attack others.

Except Jordan, Syria, Lebanon, Iran...

or is greenland better? Venezuela or Greenland?

Give me Greenland and I won’t attack anyone else except Cuba! And Mexico! And Columbia! And Canada! Obviously we're not done with Venezuela yet... then there's always Iran....

Nobody wants Russia

History doesn't repeat itself, but it often rhymes -- Not Mark Twain

3 things

1. Without the US, Europe has significant capability holes(satellite, logistics, ground launched missiles, nukes)

2. Multiple smaller armies might be, in theory, an order of magnitude "stronger" than the Russian military but because of inefficiencies, overlap capabilities and lack of unified command structure and organizing, they are effectively a circus that cant do much.

3. Not all Europe will react the same and with the same urgency. A crisis(like russian soldiers occupying a small Baltic town) by definition will create huge cracks within Europe.
