There are two world leader who sided with Germany and signed a pact. The first being Benito Mussolini, leader of Italy, signing the pact of steel. This pact declare the alliance of Italy and Germany. The second being Joseph Stalin , leader of the Soviet Union, signed the Molotov–Ribbentrop Pact. This was a non agression pact that states that both Germany and The Soviet would attack and conquered Poland.
According to the Declaration, the king denied life, liberty and happiness by preventing the colonists from establishing their own laws, making them in a way "prisoners" to the laws dictated across the sea which shouldn't have to apply to their life in the new continent.
Also by prohibiting them from trading with the rest of the world, the lives of colonists in America became dulled with the inability to reach out and expand their vision.
And finally by keeping armies in the new world during peaceful times and forbidding the new citizens to receive trial by jury.
The treaty of non-agretion between Germany and the Union of Soviet Sociacist Republics also called as the Molotov-Ribbentrop Pact was a neutrally pact between the Nazi Germany and the Soviet Union signed in August of 1939.
The clauses provided a written guarantee of non-beligerance by each party towards the other and a commitment of no alliance with an enemy of the ohter party. In addition the treaty contained a secret protocol in which they defined the borders of the so called "spheres of influence" in the possible events of an invasion to Poland, Lithuania, Latvia, Estonia and Finland.
After the signature of the pact Germany and the Soviet Union invaded Poland with a few days of distance between both operations and the new borders was set up by the secret protocol.
The secret protocol was just a rumour untill it was made public at the Nuremberg Trials.
I hope this answer have helped you. Regards.
