US desire to create a buffer zone in Eastern Europe

Explanation:

After the World War II ended, the countries that were on the wining side started to negotiate about how the continent would be divided, organized, and of course they tried to implement and force their own ideologies. This immediately created lot of tensions between the USSR and the US.

Among the numerous things on which the USSR and US failed to make an agreement, was also the US desire to create a buffer zone in Eastern Europe. Basically, the US wanted the territory from Poland's western border to the USSR's western border to be a buffer zone.

The USSR didn't fancied this. Instead, the USSR saw all territory in Eastern Europe as its zone of influence and control after the war, and on top of it it planned on making it its stronghold. What the US was suggesting was seen as conflict of interest, but also a military threat on the border, so immediately the tensions rose between the two.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
