So what? Even a united middle east is not even going to come close to being able to threaten Europe conventionally.Well, world events can change pretty quickly and can sometimes be difficult to predict.
One scenario might be.... An Israeli/US attack on Iran causing pro-western goverments in the middle east and possibly Turkey to fall and be replaced by radical islamic regimes, possibly uniting against the west. Add to this a more militant Russia if events escalate in Georgia and Russia's reaction to an attack on Iran.
I'm just saying its a good idea to leave a little excess capacity, not too trim too far. Leave a little margin for error/unexpected events.
With what?
And a new Russian threat is also not going to come out of the blue. Right now the Russians would have a hard time trying to deal with the european part of NATO only and this is not going to change in the near future.
What I am afraid of is that one day we might need to get back to cold war levels but our politicians are not willing to take the necessary steps.
If this is the case than some hundred old Leopard IIA4 are not going to save us anyway.
Remember that storing such equipment and keep it maintained is not cheap at all. I agree that we should have some Leopard IIA4s in storage. Atrittion is the key word here. But nowhere near to usefull reserve numbers.
As much as I love our heavy forces I don't think that we need that many of them.
