They do not have the foresight to look at the global market for military aircraft and build what is needed.
Er, A400M anyone? With C-17 line closed (ish) and older C-130s retiring there's a potential global market for about 400 of the type over the next 30 years (including the USAF)
Lots of nations require new tankers, lots of nations require new and capable MMA/MPA, lots of nations require new ELINT/SIGINT/AEW platforms - but where are these in Airbus' product line?
Tankers - A330 MRTT? MMA/MPA - C295 Persuader (HC-144 in USCG service) and FITS-upgraded P-3s for Brazil and others? ELINT/SIGINT/AEW - C295 AEW?
I can't think of any other defence company (including Boeing) that has the wide-ranging portfolio of Airbus Defence and Space (Airbus Military is so 2013).
