Some questions?
First of all what do you mean by "stronger" as in OTL the WP wasn't considered weak or ineffective for what it was organized to do.
The POD of this TL is the end of WW2, the Soviets not only got the bulk of German knowhow but Germany as well.
1) Considering the bulk of German "knowhow" was terrified of the Russians, (with reason actually) and did their level best to avoid capture by them what's the reason for their change of heart?
2) Considering the Soviets OTL ignored the Germans they DID capture in favor of their own development programs why would capturing "more" mean they would utilize them any more than OTL?
3) France and England, (specifically France though) were vehemently opposed to full Soviet control of Germany as was the US and doing so would run into violation of previous agreements. Not that Stalin wasn't capable of doing so if he wanted but it would have meant very possible armed conflict with the West and even more (and firmer) opposition to the formation of the Warsaw Pact in the first place.
USA Lost the Space Race when Apollo 10 exploded ending USA landing on the Moon, Russia landed on the Moon.
By Apollo 10 (May, 1969) the US was fully committed to winning the race to the Moon and they "technically" had until January 1970 to do so and could easily have spun/PR-ed the race into 1971 to achieve the goal. Sputnik seriously panicked the US and that led directly to JFK seeking a goal that was within, (even if just barely) reach of the US but would clearly be harder for the USSR to achieve. That ended up being the Moon and once started the moment would have been very difficult to stop even if Kennedy hadn't been killed.
The Soviet Lunar program was a mess and it would take significant changes to make the competitive in the same time frame. Not that it can't be done, (because lets face it I'm planning on doing so when I get around to it) but the most likely outcome of the US "quitting" the Moon race if the Soviets not going either. (The had already stated by that point they weren't interested in "racing" the US and would or would not get to the Moon on their schedule)
the Warsaw Pact became the strongest bloc in Europe Nato unlike in are world became a limp reaction like the Warsaw Pact in our world.
Why would NATO be a "limp" reaction? The stronger the WP is the more the nations that make up NATO would ramp up as well. Note that in OTL no one considered the WP to be push-overs or weak opponents. NATO fully expected to get hammered in any conflict versus the WP and the plan was always to simply try and hold on until significant forces from North America were able to be deployed in Europe. The only thing "limp" about the WP was the commitment of the non-Russian members to the idea of full out war with the West/NATO and for similar reasons the European members of NATO were less than thrilled with the prospects of WWIII; Everyone knew that the ones getting smashed into paste would be Europe with the US and Russia being "mostly" as support/supply until/unless the strategic nukes started flying at which point the results would matter even less to the survivors.
The Nation of Canada due to Communism Nations power and unity unlike in our world Red China and North Korea, Korea is all Red
LW
Not clear what you mean here, Canada goes Communist? Pretty unlikely at best and if you mean Communist "unity" then Mao has to be eliminated as his and the Russian version/vison of Communism where incompatible. A fully Red Korea is possible but it would take something significant diverting US attention AND delaying till the US fully pulled out of Korea which is more unlikely to happen if the Soviets are getting grabby in Europe already.
Really an interesting premise though and I anticipate seeing how the issues are resolved.
