I'm not an airman, but I am a politician. Picture this scenario, which I consider to be very realistically possible:
We hire the Irish firm to tank our military aircraft. Then a government is elected in the Irish Republic that is militantly anti-nuke, much as New Zealand's was/is. The Dáil Éireann (Irish house of commons) passes a law that prohibits any Irish company from commercial ventures involving nuclear weapons in any way "for safety reasons". Goodbye refuels for B-2's, B-1's and B-52's.
Or....the Dáil gets infected with the currently fashionable European antisemitism and forbids Irish companies from doing business with Israel. Israel is attacked and urgently needs resupply from the US...
You get the idea.
Contract terminated for material breach, Irish company forfeits political risk bond and most likely cannot afford penalty clauses, air and ground assets get seized by US government, contract re-let to qualified bidders.
Political risk is a part of doing business, and gets dealt with very aggressively. I had a contract to provide computer software to a foreign government, and some of the contract terms revolved around "and what happens if you idiots throw Reagan out next year?" (The government was and is friendly, but was and is not flavor of the month with Democrats.) I had to make a real gut check on that contract--if Mondale had won in 1984, my company would have gone under.
I got the IDEA so figure3 this out. I want my BROTHERS to get the FUEL they need.
