Russia is not weak, Putin has millions who will run to their death with open arms into Poland. How many Poles are willing to die to stop him? He could send 400 Jet drones into Poland every night, how do you propose you stop him? 10's of 1000's of Russian saboteurs in the EU, how do you find them? You even have Political Parties that want to enslave their own people for Russia. Iran hasn't lost its grip in 40 years, the USA doesn't have the resolve to finish what they started or protect Europe.
Tell me how you would solve all the other issues, I am interested.
