Counteract between powre, policy and geography in importantstraits of the world

We have been faced considerable developments in maritime trade after 2nd worldwar. Development of maritime trade led to considerable dependence of countries tofree shipping. Thus, maritime issues are considered as subset of national security. Thisis because access to capital and market is important factor of world new order and itdepends on sea lanes and important straits. Therefore, main security concern,especially in relation to opponents, requires precise strategic consideration forconfrontation with trade wars. Thus, this issue is reason for what cold warconsiderations are invalided and new problems are posed in front of countries.Alongside with ever-growing importance of maritime trade, international straits alsohave special position in sea new geopolitics. Although important straits had key role inpast too, but currently they are important economically. This issue in time after coldwar is reason which reduces importance of some straits and gives some other straitsspecial importance due to position that they have in world trade routes.This research along with considering changes made in meaning and context ofstrategic straits in two geopolitical periods, tries to analyze effects of policies andpowers on these straits. Results yielded from this issue indicate that Indian Ocean andits important straits due to key role that they play in maritime trade, they are veryimportant and this is reason of competition between world powers in these straits.
