Was Britain justified in entering World War 2?

>>2681800
yes they had an alliance with Poland

however this means they should have declared war on the USSR as well

>>2681800
Britains goal for the previous two centuries was to stop any one country from dominating mainland Europe, WW2 was for the same reason. Hitler did not want war with the UK and offered peace numerous times, Britian should have allowed Hitler to do what he wanted with Poland (this is what Britain done anyway) and allow him to invade Russia as much as he likes.

No.

Really France should have honored their guarantee and declared war after Czechoslovakia. Britain would have had a slightly harder time selling the war to public opinion without the "peace for our time" farce, but allowing Hitler to take Czechoslovakia which could have actually defended itself was a dumb move. Especially when Poland were just as opportunistic as the Nazi's or Soviets were and took their own piece of the Czechoslovakian land. Their guarantee was just the Eternal Anglo looking for any excuse to try to stem the Nazi tide they had allowed to swell up so much.

The Anglo-Polish military alliance stated very clearly it was triggered by German aggression, not soviet.
