Remember: government walls can be used to keep people in as well as out.

Key issue is which way do the machine guns point?

[BaalChatzaf]

I like the idea of the machine guns pointing toward the fence. That way people coming through illegally can be blown away on their side of the fence.

I am the grandson of immigrants. My forebears come across the Atlantic on the bottom of boats and entered the country legally.

If we let the Child Crusade arranged for us by the Coyotes succeed, this country will be swamped by urchins. We must not let our survival be overcome by sentiment.

Correct.

Seems out government can not distinguish the difference between immigration and invasion.

The Berlin Wall was a rarity. One of the few walls built to keep the entire population of a Nation in.

On the other hand there is no topological difference between a closed simply connected region on the surface of a sphere on the inside of the region from the outside of that region. A 1/z mapping establishes the topological homeomorphism of the two.

The inside of a circle can be smoothly mapped to the outside of a circle by w = 1/z where w and z are complex. All that is required is the removal of one point from the spherical surface.

Apparently, that is not entirely true.

Apparently, we do not call a "wall" a wall anymore, it is now a "separation barrier."

Here is the Wiiki:

Separation barrier or separation wall refers to a barrier, wall or fence constructed to limit the movement of people across a certain line or border, or to separate two populations.

Fence at Israel-Egypt border near Nitzana, 2007.

The term is used to describe the various fences, walls and other barriers Israel created to separate Palestinians in the Israeli-occupied territories of the West Bank from Israel so that they may not enter Israel without authorization.^{[citation needed]} Barriers also have separated various Palestinian towns and villages within the occupied territories from each other and they separate Egypt and Jordan from Israel.^[1] Israelis prefer the term to "wall" since only five^[2] to ten percent of it consists of wall and most of it is barbed wire or non-wall structures.^[3]

David Henley opines in The Guardian that "separation barriers" are being built at perhaps record-rate around the world along borders and do not only surround dictatorships or pariah states.^[4] The term "separation barrier" has been applied to such walls, fences or barriers in Cyprus, Kuwait, Saudi Arabia and the United States.

Of course, the Jewish state is listed first.

Early barriers

• Tegart's wall: The British Mandate for Palestine constructed a fence on the northern border of Palestine to separate populations in 1938 following the recommendations of Charles Tegart. The fence was later dismantled.^[5]
• Jerusalem: From 1948 until 1967 Jerusalem was divided, with Jordan occupying the eastern part of the city, which was divided by walls and barbed wire until Israel pulled them down after the 1967 Six Day War.^[6]
• Lebanon, Jordan, Syria: Since 1948 Israel has maintained fences and barriers along its 80-mile northern border with Lebanon—including what is called the "Good Fence"—to prevent attacks from Palestinians who are refugees in Lebanon,^[7] as well as fences at its borders with Jordan and Syria.^[8]

Israel-Egypt separation barrier circa 2012

• Egypt: A rusty low fence divided Israel's 155 mile Sinai Peninsula border with Egypt. It was often crossed by smugglers and Bedouins whose tribal lands straddle the border.^[9] In 2010 Israel began building an electric fence with surveillance to keep out migrants and asylum seekers.^[10]
• Egypt-Gaza Strip barrier: In 1979, after the signing of the Egyptian–Israeli Peace Treaty, the two nations created a 14-kilometer-long, 100-meter-wide strip of land, the Philadelphi Route, as a buffer zone between Israeli-occupied Gaza and Egypt.^[11] It includes the Rafah Border Crossing between Egyptian and Palestinian-controlled Rafah. Israel built a stronger corrugated sheet metal and barbed-wire barrier as part of a larger 200-to-300-meter buffer in the Philadelphia corridor during the Palestinian uprisings of the early 2000s.^[12][13]

And now to the rest of the world:

Cyprus Since the Turkish invasion of Cyprus in 1974, Turkey has constructed and maintained what economics professor Rongxing Guo has called a "separation barrier" of 300 kilometres (190 mi) along the 1974 Green Line (or ceasefire line) dividing the island of Cyprus into two parts, with a United Nations buffer zone between them.^[43]

Egypt The Egypt-Gaza barrier is often referred as "separation barrier" in the media.^[44] or as a "separating wall".^[45][46][47] In December 2009, Egypt started the construction of the Egypt–Gaza barrier along the Gaza border, consisting of a steel wall. Egypt's foreign minister said that the controversial wall, being built along the country's border with the Gaza Strip will defend it "against threats to national security".^[48] Though the construction paused a number of times, the wall is nearly complete.

Kuwait Writer Damon DiMarco has described as a "separation barrier" the Kuwait-Iraq barricade constructed by the United Nations in 1991 after the Iraqi invasion of Kuwait was repelled. With electrified fencing and concertina wire, it includes a 15-foot-wide trench and a high berm. It runs 120 miles along the border between the two nations.^[49]

Malaysia Renee Pirrong of the Heritage Foundation described the Malaysia–Thailand border barrier as a “separation barrier.” Its purpose is to cut down on smuggling, drug trafficking, illegal immigration, crime and insurgency.^[50]

Saudi Arabia In 2004 Saudi Arabia began construction of a Saudi-Yemen barrier between its territory and Yemen to prevent the unauthorized movement of people and goods into and out of the Kingdom. Some have labeled it a "separation barrier."^[51] In February 2004 The Guardian reported that Yemeni opposition newspapers likened the barrier to the Israeli West Bank barrier,^[52] while The Independent wrote "Saudi Arabia, one of the most vocal critics in the Arab world of Israel's 'security fence' in the West Bank, is quietly emulating the Israeli example by erecting a barrier along its porous border with Yemen".^[53] Saudi officials rejected the comparison saying it was built to prevent infiltration and smuggling.^[52]

Slovakia BBC reporter Nick Thorpe described a 150-meter-long and 2.2-meter-high wall in the Slovakian town of Ostrovany as a “separation barrier” and compares it to the Berlin Wall and the Israeli separation barriers because it is meant to divide the two-thirds majority Roma population from the native Slovaks. Slovaks accuse the Roma of stealing their fruit, vegetables and metal fence posts.^[54]

United States The United States has constructed a barrier along 130 kilometres (81 mi) of its border with Mexico of 3,169 kilometres (1,969 mi) to prevent unauthorized immigration into the United States and to deter smuggling of contraband. The Georgetown Journal of Law has referred to it as a "separation barrier" and suggests that while it is "revolting to many as an ugly face of separation" it could be used as an opportunity if part of a larger program of "foreign aid, infrastructure investment and regional development."^[55]
