“We do, the Baltic countries are NATO countries.”
They should have done this decades ago. They know the Russians, why did they wait?
If you mean the build up, that is what President Trump was telling them, and why he was moving troops to Poland and launched a nuclear buildup and withdrew from the INF treaty, and started sending weapons to Ukraine and threatening NATO slackers.
Europe was grown complacent and even depended on Russia for energy but this invasion and launching the biggest European War since WWII has forced everyone to wake up.
Even our allies in the Pacific have reacted to this Russian invasion. This invasion has shaken the world and and a lot of stale militaries, it was a splash of cold water.
