Few weeks after that, Venezuela saw a naval blockade of several months imposed by Britain, Germany and Italy over Castro's refusal to pay foreign debts and damages suffered by European citizens in a recent Venezuelan civil war. Castro assumed that the Monroe Doctrine would see the United States prevent European military intervention, but at the time the government of president Theodore Roosevelt saw the Doctrine as concerning European seizure of territory, rather than intervention per se. With prior promises that no such seizure would occur, the US allowed the action to go ahead without objection. The blockade saw Venezuela's small navy quickly disabled, but Castro refused to give in, and instead agreed in principle to submit some of the claims to international arbitration, which he had previously rejected. Germany initially objected to this, particularly as it felt some claims should be accepted by Venezuela without arbitration.
