SOVEREIGN nations have typically resolved bilateral disputes through formal or informal negotiations. There is invariably some give and take, though sometimes one side may feel compelled to take some coercive action, like trade or military sanctions, against the other. However, not all disputes are stand-alone, like territorial claims. Friction between countries is now more likely to consist of a continuing series of small and mid-level issues, increasingly economic in nature. The information and media revolution has dramatically increased the general level of people's knowledge, involvement and debate on national issues, and governments are now finding that negotiated settlements (which involve written commitments) may be risky due to pockets of resistance in the home country. The scope for unilateral penal action has also been reduced, or at least its attendant cost has increased, due to global interlocking of interests and the ability of the other side to retaliate. The US could easily impose a total economic embargo on Cuba in 1962 but, under threat of European retaliation, it has just recently been forced to suspend the Helms-Burton bill which would have penalised those overseas companies which profit from expatriate Cuban assets.
