Sims, 1st thanks to show Port in the game 
Now, on the real business:
I am against what you said. I even think that once a country enter in war with you, whether you respond or not, the MPPs should be activated! Otherwise, what are them for? "So, if you are being attacked, we will only defend you if you show us proof that you were not the 1st to attack"? No,if the CIV is your ally, it is your ally. Or else we could here suggest the cration of something else.
Like: a new MPP like you suggest and a Military Alliance like the one I suggested.
What about this?
