The ports of the West Coast of the United States have historically been very important for the development of the country. From the date of independence, when the country only had ports in the Atlantic Ocean, it was understood that bioceanity was crucial to convert a nation into an economic power. The American expansionist plans, based on the doctrine of Manifest Destiny, sought to reach the Pacific Ocean.
These ports allowed the United States to expand its commercial influence to the Pacific Ocean, extending its commercial network to nations such as Japan, China, India and Australia, among others, who over the years have become great commercial partners of our country.
Thanks to this commercial expansion, the United States also gained a great geopolitical influence, for which bioceanity played a fundamental role. Today, America is influential both in the Atlantic Ocean, which connects it with Europe, and in the Pacific Ocean, which brings it closer to the great Asian markets.

When Napoleon needed money, he sold Jefferson the Louisiana
Purchase, which he had acquired when he conquered Spain. To find out what he'd
just purchased, Jefferson sent Merriweather Lewis and William Clark to explore
it. It covered an area from Louisiana northward to Missouri and across the
biggest part of the Great Plains and Northwest. The team which went with them
included such diverse people as Sacajawea, a Shoshone Indian and her baby Lewis's
slave, French trappers, woodsmen, and other interpreters. Lewis concentrated on
cataloging what they found, such as the various Native American tribes,
animals, and plants, and mapping the region, while Clark was the woodsman who
led the expedition. They went through many hardships, though miraculously only
one member of the expedition died over the several years they were gone. At one
point they were starving in the Rocky Mountains--there was not enough fat on
the deer they shot to keep them alive. They found an Indian tribe to barter
with, but the chief refused to deal with them until Sacajawea walked in--she
was his sister, who had been kidnapped from the tribe at the age of 5! Needless
to say, they got their food. They made it to the Pacific Ocean, where they then
split into two groups, one of which took a more southerly route back.
Under the leadership of Prime Minister Neville Chamberlain, the United Kingdom originally undertook a policy of appeasement by which they let an increasingly aggressive Germany become more belligerent in the hopes that they would tucker themselves out and be satisfied after invading a few countries.
