not possible

In all honesty, I hate to sound pessimistic, but it is simply a necessity in this situation; the Great Capitalist Peace simply is not a realistic goal. The major flaw lies in the initial assumption that all states act in order to earn money - most easily achievable through capitalism and thus allowing for peace through security created by economic dependency upon one another. Individual humans are indeed greedy and would certainly agree to most money-making opportunities, however, there are some things that outweigh even that nearly instinctive desire such as ideals and religious beliefs. If religion can convince suicide bombers to willingly sacrifice their lives to kill others, how can we expect bribing them with a position in the global economy to deter their violent actions? It's true that governments with stronger economies would have more resources to suppress terrorist activity, but what of those governments being run by terrorism, or those with a large investment in it? They are not likely to give it up easily. These contributors, personalities and ideas, will survive no matter how many countries are invaded and governments coup d'état-ed. Peace, capitalist or otherwise, is simply not achievable in the long term on a global scale due to inherent human nature that, despite greed, will sometimes act according to strong beliefs, ruining all hope for a permanent establishment of capitalistic peace.
