Perhaps if the cost of war is be higher than the cost of piece, wars will become less frequent. In fact, to some degree this happened over the 20th century, especially in Western and Socialist countries. With the established view that countries may not expand through military conquests, it is harder to justify a war even to own population. 

But sometimes reasons for aggression go far beyond pure economic considerations. If the population, or political leadership, perceive a danger from another group or country, they may feel that the war is the only way to remove the threat. They may be willing to take any economic risks for a good while if they feel their core values are at stake. 

So **reducing the perception of threat** and **increasing the level of trust between neighbor countries or population groups** may be key to reaching world peace. One of the ways is intensifying economic connections between entities – with the crucial condition that  such connections are mutually beneficial and there is a working, trusted way of resolving disputes.
