Lyric discussion by special 3lend 

i didn't know this at the writing of my first comment, but laika is the name of the dog sent into space by the russians with no intention of retreiving her back to earth.

i can see how that ties in to the song...

I definitely think it has to do with the Russians. But I think it is actually about Alexander, Vladimir Lenin's older brother. He was considered a terrorist by the Russian government and executed. His death had a profound influence on Lenin. "They should have named you Laika" could be a comparison in similarity. Laika was sent to space for a Russian mission, while Alexander tried to start a revolution through violence, and was later imprisoned, murdered and forgotten. "When daddy comes home you always start a fight" could refer to the fundamental disagreement in the Ulianov family. That's just what I feel...

Also I'd like to put out there that they wrote a song for Dark Was the Night called Lenin.

@tifnz Interesting! I think you're on to something.

@special3lend That's also what I thought about when I Googled the name "Laika" and found out it was the dog they first sent to space.
