While scrollling on quora, i saw a question about world wsr 3 and some people are already saying the USA cant invade RUSSSIA and the British cant invade india....
I wsnt to ask is it true
Note: don't judge based on YOUTUBE RANKING OR GOOGLE RANKING

The issue with UK is that they have scaled down their military over the past years. Practically UK cannot afford a war with a country that has nuclear weapon which India is part of.
That of America, it is possible but whether they can hurt Russia remains the question. Russia has everything USA has except one thing- global spread of military. This means USA can easily surround Russia from their bases all over the world.

Above all, we need peace, at least relatively.

Iraq Vs Saudi Arabia with Saddam in power in Iraq.
No match, the Iraqi Republican Guards would drink tea
in the king's palace in Ryad , only 24 hours after the beginning of the war.

USA cannot successfully invade Russia, conventionally ,those who can't successfully defeat north Vietnamese soldiers can never defeat Russia.
In terms of nuclear war, Russia's dead hand has been reactivated since Trump withdrew from the INF treaty, if radiation of a reasonable amount is ever detected in Russia, US will be bombed back to the stone ages. If any of the link in the chain in command of Russia is missing, the same will happen. And it is controlled by artificial intelligence, kill all Russians and Russia will still be able to destroy the US

Great Powers are divided in tiers now,
First Tier is US, Rusaia & China
Second is India, France and UK
Third may be Japan & Korea etc..
The powers in two successive tiers have great gap between their powers. Russia will soon fall down to second tier and UK even lower while India enters first in upcoming decade.
