Current climate
I've signed mainly because if I can do anything to help the lads and lasses then that's a good thing.
Wasn't the Eurofighter thought of being in a European Airforce, I think the Navy had similiar plans for a joint warship, and mainly because Terry (Taliban) hasn't got any fighter planes.
...and bombing them isn't working.
There is also little interest in operations in Afghanistan from our European neighbours, obviously I'm not privy to the "bigger picture" but it does seem the traditional fighter is not proving its worth in this particular war. So it would be wise to spend it on something else like IED detection for the Pongo's (Army), but then the MOD never does anything sensible too many chiefs.
