"Game is mostly full of passive loose players with 1 or 2 loose aggressive foreigners."
If this is true? Why the raise to JUST $40? I have to know. What were you hoping to achieve? Were you hoping someone would rr you? And you could trap? In a 2/5 game, your raise to me says 88-JJ. Make it 70-90, if all four of them still want to call then good luck. Make them PAY to see the flop, obviously with a raise to say 85, EVERYONE at the table knows you have either KK or AA. This is why you need to make them PAY to see it. Do you think a raise to 40 is really going to do anything when everyone is SO DEEP? Your just building the pot. Put the pressure on your opponents, especially with 5? To act behind you, you have to assume two of them are going to call you with just a raise to $40.
RAISE MORE PRE and you possibly don't get yourself into this situation.
BUT if you raise to say 85 and get two callers, with how deep you are, your NOT commiting yourself to this hand. I think too many players get married to AA and don't seem to realize you CAN still fold on the flop/turn. In this case, with 4 callers and that flop, I'm folding.
Flop: Fold on flop, TERRIBLE flop for AA, MAYBE I could justify a call if I had the A
otherwise don't call $50...there's too much out there that has you beat, two pair, sets, straight, possible flush/nut flush draw. To me its, highly likely one of them flopped a set on you, with already 4 people in the hand I can see one of them calling with a hand like 44-77 because there getting such good odds.
