First of all I would like to point out how hypocritical you sound, you speak of the British as being "parasitic" and "the cause of both world wars". If you studied history you would know, firstly that the kaiser mimicked every detail of the British military outfit, in the years leading to ww1, including its navy stating he was the monarch to a young empire and was just trying to keep up with Britain and to a lesser extent France,

Secondly hitler himself admired the British empire stating "that is how I will run things, first divide then conquer and finally exploit it" which is exactly what happened with France hitler successfully divided France leaving Vichy France and occupied France fighting with the french resistance (free French army) he then conquered by invading Vichy France thus bringing all of france under his control and finally exploited it by taking all its resources to fuel the German war machine, especially the forced labour of 600,000 French men who were taken to work in factories in hamburg and such against their will.

"English declare war on Germany for supposedly "invading" Poland, yet, no such declaration against Russia when it invaded Poland as well?"

The answer to this is simple and it's not "wall street" or "bank of England". The western allies Britain, France and the USA were all extremely afraid of fascism spreading throughout Europe and indeed the world they were equally as afraid of the communism spread, but those two political ideologies "fascism" and "communism" hated each other more than anything that's why Britain and France were so confident declaring war on the nazis and not the Russians because they knew eventually Russia or Germany would break that phoney non-aggression pact and the nazis would then be caught in a vice, being dragged into a two front war. Both germany and Russia had reasons for signing the pact Germany needed time to try and neutralise Britain and France without Russia getting involved and Russia needed time to build up numbers and equipment capable of defeating the Germans.Another reason no action was taken on the soviets was because The Soviet government announced it was acting to protect the Ukrainians and Belarusians who lived in the eastern part of Poland, because the Polish state had collapsed in the face of the Nazi German attack and could no longer guarantee the security of its own citizens. Facing a second front, the Polish government concluded that the defence of the Romanian Bridgehead was no longer feasible and ordered an emergency evacuation of all troops to neutral Romania.
