Boroda! Sheep head is a compliment for you. It is also a delicatessen in my country! Hmm, maybe I'd rather use the term "mutton", which expresses lack of intelligence.......
Now, on to the first (meehh):
"Americans decided not to take money for lend-lease from UK and other allies except USSR."
Well, they DID, and Britain was Bankrupt from 1940/1941 onwards because of it.
It was paid with gold, firms, estates, stock and technical info.
You must have been hit by Pravda there
(or TASS, who declared 2-3 days after the Finland invasion that there was a new "Peoples government" in Finland")
Now, onto the Tirpitz/PQ-17 affair.
PQ 17 is a very sad story. Tirpitz actually turned around after some of its escort destroyers ran aground (N-Norway is still notorious for unexact charts). The Brits took the very questionable decision to scatter the Ships, which left them as easy pray for German subs and planes.
They were not avoiding Tirpitz, on the contrary, they were looking for the Tirpitz, with a trailing task group. The British did indeed absolutely engage the Kriegsmarine in surface battles, as you should well be aware off, loosing ships, but usually sinking the big ones as well. Well, they sank 3 out of the 4 capital German BB's, and crippled the fourth. RN 2, RAF 1 +1. The value of PQ-17 was vast, of course as you put it, worthless, crappy aircraft and so on, but well, here you go:
"Its cargo was worth a staggering $700 million. Crammed into bulging holds were nearly 300 aircraft, 600 tanks, more than 4,000 trucks and trailers, and a general cargo that exceeded 150,000 tons. It was more than enough to completely equip an army of 50,000."
My great uncle flew for the RAF at the time. He was to be sent to Russia with his squadron along with more squadrons from the RAF. Their planes never arrived in Russia, so they were re-routed to the N-African Theater. There, the RAF was doing well enough for LW squadrons to be routed FROM Stalingrad to N-Africa, incliding i.e. famous LW ace Heinz Baer.
The Battle at Kursk is no doubt the biggest land battle fought in WW2. The battle at Stalingrad was also very very big, I am fully aware. So was Normandy. So was Anzio. So was El-Alamein.Please do not fail to realize that had the RN, RAF, USSAF, British Army, US army, and the factories of those nations not been on the job, the USSR would have lost. Germany could have unleashed all their might against the USSR with no other front. And without the allied bombing campaign going on, the German manufacture and supply status would have been a lot better off.....
If you want some stats for comparison, I'll try to help you
BTW, the soviet fighting method demanded many times the troops of anything known so far. Or as Zhukov once put it: "When my troops enter a minefield, my troops move over it as if it were not there"
