In essence you are right but British troops never took oath to jump in fire on the call of Uncle Sam but thats what UK has been doing for decades loosing thousands in "friendly" fire and hostile fire.
NOW NOW NOW
dont get upset and read what assassinations caused the first great war? why everyone jumped in resulting in millions of deaths?
just Like American and Israel have special relationship we have one with Saudis too and yes if it comes to sacrificing our lives for the Kingdom we will do it. its about our roots of religion as well.
