You’re quibbling over the word “most”.Â
I agree that the UK is our most important military ally but we have overwhelming other support from Europe through NATO.Â
 What other support do we have in the Middle East?
 What are the “most” important issues? Military strength or intelligence that might head off the need for military action? It’s certainly debatable.Â
I honestly wouldn’t argue with any points on which if the most critical to our interests. I am sure that people can make valid arguments from different points of view. Military? The UK. Middle East intelligence? Israel.Â
As far as Israel, SmashMouth said that they “may very well be” the most important.
”May be” is not an adamant statement but a suggestion. They might be… depending on what the discussion is about.
Worrying about the word “most” (especially “may be”) seems to be the definition of trivial.Â
