You see guys the problem we have in the world that public info is all wrong and people belive into wrong things.
It's like everyday people beeing told that ruler has clothes yet they are naked!!
Now let's explain about NATO specially UK france and germany in history they never been about defence they been attacking for example UK 400 years Ago was like pirate you did not pay % they bombed your Vessels.
France invaded africa so again it's attacking - both france and germany have try to invaded and attack Russia hitler and Napoleon both of them.
So when we talking about whos good at DEFENCE then it's russia because they got historical experince how to protect themselfes and use defence.
THATS WHY RUSSIA FAILED IN UKRAINE BECAUSE THEY HAVE NOT EXPERINCED WITH ATTACKING !!
the ukraine / russia situation can teach to nato members about defence from ukraine now the UK and other NATO members can learn about defence since the NATO alliance nations are all about attacking and invading and colonisation and have little experince about defence only country wich have some kind of defence experince are UK when germany did attacked London but the rest of the Europe Nations most of them are predators and attackers.

Now the situation is very clear! Europe is afraid of Russia but  russia is weak attacker but great on defence!
Europe is good on attacking but weak on defence !
Now russia can practize and learn about attacking in ukraine so If they manage to invade ukraine then there is little hope they could attack Europe and same time europe nato can learn defence by watching the ukraine situation.
