Russia and Ukraine

[Leonardo17]

They went into WWI after Bismark sunk one of their ships and so they went in “To protect democracy and human rights”. This scenario repeated itself in WWII.

WWI:
Bismarck died in 1898. He predicted a war 20 years after his death if the German emperor would not continue Bismarcks policies.
The sinking of the Lusitania was indirect a result of Tritpitz´ fleet program, which was however focused on surface combat.

WWII:
Germany declared war on the USA!!!!!
Although, the US had already been heavily supporting the UK with the "Lend and Lease" program, flying patrols over the atlantic (one of which detected the german battleship Bismarck), and a US WWI destroyer was sunk by a german sub (or was it only an attack?) before war was declared. Anyway, the destroyer was on pretty agressive sub partol duty.
So, its a bit complex, but Germany declared war on the US, period.

- Yes. I think I should check my Wikipedia more often.

I just don’t remember all the details. Sorry.
