Given that everyone - except for Team Timmy - is in the periphery, and the alternative is letting you blob in Spain and let you pick them of one by one, I would know what to choose.
Furthermore, there's no way they'll destroy you in one session.
They have to attack you and do it soon, or they are giving up already.
Have you looked how much development is still left in Spain? Not much. My growth into AI will grind to a halt when I run into the France/Mamluks blob (my allies' AI growth has already long halted), whereas Russia and Prussia have a completely empty Scandinavia and HRE to expand into, and the players positioned in Europe are quite weak and won't be a match for them when they come knocking. -Especially- not when the inevitable partition with Mamluks happens.
The issue is the same for Mamluks, who have entire Africa to expand into and the perfect springboard to go colonialist. If the Ducat party gangs up on the Turks, the only thing they'll achieve is that, rather than having one team to contend with, they'll be held in a vise by Mamluks (coming from Iberia and into Italy) on one side, and (P)Russia on the other.
The same again for Timurids. Focusing on us means they'll be left in a vise between (P)Russia and India, and possibly even Mamluks.
The only two teams who have any real direct interest in eliminating us would be the two teams who otherwise would have nobody checking their moves, i.e. (P)Russia and Mamluks. Is it a coincidence they are the ones to instigate action against us the most?
