You might have something there Hess. The Russian market is one of the biggest Irish Beef importers, meanwhile Irish farmers are being paid for empty fields. Answer, increase beef production and do a deal with the russians.
As for aircraft, no money concerns, it would have to be a version of the SU27. If a budget is required then a version of the Mig 29 should suffice.
As regards maintenance they are termendously tough aircraft designed for field maintenance with no special tools or equipment the main problem is TBOs on parts such as engines. Mind you engines from russia are dirt cheap. Believe it or not you can pick up a good mid time Walter turbo prop for the same price as a western piston. I imagine the military jet engine market being much smaller would also allow for cheap deals.
