More details about Reagan's defense spending:

When President Ronald Reagan came into office in 1981, he took a hard stance toward the Soviet Union.  Where previous leaders of the nations had pursued detente and nuclear arms reduction, Reagan spoke of the Soviet Union as the "evil empire" and ramped up American military preparedness with the Stategic Modernization Program.  He authorized a program to spend over 200 billion dollars over five years on bombers, cruise missiles, intercontinental ballistic missiles, and more.

Then in 1983, Reagan proposed the Strategic Defense Initiative (SDI), which was a plan for a space-based missile defense system against any threat of Soviet missiles.  Sometimes people referred to Reagan's plan as "Star Wars."  More than 200 billion dollars were devoted to the Strategic Defense Initiative over the next four decades after the program was started.

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.
