What he's saying is that before TPF's allies dive in head-first, they'll want to make sure that that isn't exactly what we want them to do. It's one of the stages of military planning. Attacking someone to get at their friends certainly isn't unheard of.
The governments of those alliances are taking everything into consideration before they decide on a course of action. They're taking their sweet time with it, but still. I would expect ours to do the same.
