2. The U.S. and Canada share the “world's longest undefended border.” The border was demilitarized after the War of 1812 and has remained peaceful. Military collaboration began during World War II and continued throughout the Cold War on both a bilateral basis and a multilateral relationship through NATO. Both countries are NATO members and have high military interdependency, in particular, during the Cold War against Soviet threat.
Today Canadians and Americans are in close cultural proximity, sharing the same language, similar religion and political systems as well as many values.
Their economic relations are so close (they have been each other’s No. 1 trading partner for years) that the two countries have established the North American Free Trade Agreement, the world’s largest free-trade zone. Both enjoy the most developed and richest economies in the world as well as a comparable standard of living (Canada’s welfare system is even more comprehensive and covers more widely).
To guard the over 8000-kilometer long land border is not only expensive but also unnecessary (in a sense, impossible, because it is too long), because neither people worry that their neighbors would cross the border on a large scale or stay in their country for a long time.

3. The border between the U.S. and Mexico is heavily guarded (mostly on the American side) against illegal immigrants entering the U.S. while people can enter Mexico freely. The cause is mostly economic rather than political. There is a huge disparity in the standard of living between the U.S. and Mexico whose per capita GDP is only about 20% that of the U.S. (2012 World Bank statistics). It is estimated six out of the eleven million illegal immigrants living in the U.S. are Mexicans, and millions more plan to enter the U.S. They try to benefit from the American business or job opportunities or from the American welfare system or even to engage in drug-trafficking and smuggling. Another purpose is to combat crime and terrorism, particularly after the 9.11 terrorist attacks. The U.S.-Mexican border areas witness the most serious drug-trafficking and gang violence in the world. Some Mexicans, in particular those haunted by the serious drug-related violence in recent years, try to escape from the violence in Mexico by moving to the U.S. In a word, if the US-Mexico border is open and unguarded as the U.S.-Canada border, there would be millions of Mexicans trying to migrate to America so that the consequent problems would be very difficult for the U.S. deal with.

4. Alaska, facing Russia across Bering Strait, is located between the Arctic and Pacific oceans, so it’s important for strategic position and transportation.

5. Hawaii, like a chain of beads, is located in the central Pacific Ocean, the best place to enjoy the oceanic scenery.
It is famous for natural scenery: white beach, blue sky, and palm trees, etc.
The famous Pacific Fleet is located at Pearl Harbor, Oahu Island.
