Guys, first of all i am newbie so please don't consider i am against any of these pools. I was using F2pool for around 8-9months last year.

There is a question thats bothering me last few days, its about the 51% attack.. Main 3-4 pools are all from China F2pool, Antminer, BW and BTCC. From some previous discussions on the forum Antminer and F2pool has some sort of relationship and most likely others may have too.

Anyways China is total authoritarian state and if they want they can take control of these pools without any issue. Isn't this an issue that 60-70% of pooled mining is from china? they have been trying to stop chinese money leave country anyways. Let alone the state, If just the 2 pools decide to combine the mining power they could cause an attack. Should the pools be more spread out regional wise?
