You mean the export markets where the US government twists arms in favour of the F-16 instead, and then offers "surplus" F-16s to fill the gap before production at a peppercorn rent? And exactly which A-400M exports are you refering to, or do you know something i dont?
And there is someone else to go to - Boeing and LM. Which is why most of Europe is signing up to buy the JSF and not the Typhoon and why the A-400M has had to compete for orders against the C-130J, ordered by the UK, Italy and Denmark. A d**n sight more competition than is allowed for in the USA.
It would seem to me that, until they have a bit less of a blatantly protectionist attitude to their own domestic military market, the Americans should be the last ones to take comment on the procurement practices of some of their best customers....
