Well... make it a variable that can be set before the game starts and maybe add a confirmation box so that you don't do it by mistake... Or instead of a confirmation box you have to click the box 2 times to get the alliance request sent.

Or for another idea... Have a maximum number of alliances you can create during a match... Say you ally with someone that uses up one of your alliances and if you later unally you don't get that 'slot' back. Would make you really think about breaking alliances and backstabbing people as you could very soon end up unable to ally anyone.
