The shortest Lend Lease route was from the UK the Murmansk, which is obviously the Atlantic Ocean.
Yes there were other routes, such as through the Persian Gulf and by train over Iran to the USSR, the Arctic route was significant.

We poured far fewer resources into our navy than our opponents, the English and the Americans, but we had far fewer resources to begin with.
The US is blessed with natural resources, Britain had tons of colonies.
We got results, especially from 1939 to 1942, after which the tide turned, but we couldn't simple abandon the battle in the Atlantic and we still took down allied ships, although we had increasing, heavy losses.

Ineffective management? Now I don't know about that. At least we were able to feed ourselves. You would've starved without British people literally spamming you.
But seriously, are you one of the people that are not yet convinced that communism is inherently corrupt and ineffective?
