What are the characteristics of Trump's wall?

The President of the United States has announced his determination to build a barrier wall for migrants along the border with Mexico, to the extent that he has even engaged with Congress representatives for funding. Donald Trump has requested at least five billion dollars for the construction of such a wall, and the opposition from Democratic leaders in the Senate and House of Representatives led Trump to threaten a government shutdown in recent days. However, a few days ago, the President withdrew his position on the government shutdown without explanation, and the U.S. Senate voted on Wednesday to approve the budget for several federal departments and agencies, saving the U.S. government from a potential shutdown. Trump quickly expressed his dissatisfaction on Twitter on Thursday, stating that he would not sign any bill that does not address border security. Meanwhile, according to Reuters, Trump administration officials are seeking other ways to fund the wall, intending to reallocate money previously designated for certain agencies and projects to the wall's construction. But what characteristics does Trump's proposed anti-immigration barrier wall, for which prototypes have also been built, have? Donald Trump has stated that his border wall must be 'impassable, massive, tall, strong, and beautiful,' which certainly suggests high costs. The President has said that the wall will be 1,600 kilometers long and estimates its cost at 10 to 12 billion dollars, while the Department of Homeland Security has calculated this figure to be around 21.6 billion dollars. The United States and Mexico share a 3,142-kilometer border, of which 1,100 kilometers is currently protected by walls or fences. Trump's wall is intended to replace the current walls and fences and cover most of the border's length, with no wall to be built only in areas where mountains and natural obstacles make crossing difficult. The current fences cover one-third of the border's length, and in some places, crossing these fences is not particularly difficult for migrants. The proposed barrier wall is set to be one of the tallest and longest in contemporary history, standing at 12 meters tall, three times higher than the Berlin Wall. For comparison, the wall separating Israel from the West Bank is 8 meters high. The volume of concrete required for the wall's construction is astronomical, and many companies are currently registering to supply this concrete. Hundreds of companies have submitted their applications to participate in the bidding for the construction of Trump's wall, interestingly including several Mexican companies. The head of Cemex, Mexico's largest cement company, had previously stated that he would 'happily' supply the cement for the border wall, but later withdrew his offer after significant criticism. Trump's plan for creating a border barrier does not only include the wall; a 45-meter strip of empty land will be created in front of the wall, behind which there will also be an initial fence on the Mexican side. This empty land will be monitored with cameras and various devices, and if a migrant manages to cross the initial fence and approach the tall wall, an alarm will sound, and border patrol will be notified. The initial fence will be constructed in a picket style so that agents can see beyond it and monitor individuals approaching the border. Currently, many migrants heading to the United States are from Honduras, El Salvador, and Guatemala, fleeing poverty and insecurity in their countries. Over the past six years, U.S. border patrol has detained more than two million illegal migrants along its southern border. Currently, over 12 million migrants from Mexico live in the United States, with 45 percent having entered the country illegally. Since Donald Trump took office, which has been accompanied by stricter measures against migrant entry into the U.S. and the return of groups of migrants, border cities in Mexico like Tijuana have faced an accumulation of migrants, and reports indicate that the camps and shelters in these cities have reached saturation and can no longer meet the needs of the influx of migrants. On the other hand, international environmental organizations have warned that the construction of such a wall and barrier will have a significant negative impact on the region's ecology, wildlife corridors, and flood paths. Currently, there are more than 45 long border walls and fences in the world, one of the most famous being the wall between Israelis and Palestinians.
