"Have a look at Israel, they are building another wall, their wall is 99.9 percent effective, they told me – 99.9 percent." True.
Israel built a wall along the border with Egypt in 2013, and it proved effective. Israeli officials said that illegal crossings dropped to 12 in 2014 from over 16,000 in 2011 – a reduction of 99%.
If this example can be applied to the United States it is another matter, as reported by PolitiFact. The border between Israel and Egypt is much shorter than the border between the United States and Mexico, along flat and non-mountainous land. Israel has also invested in technology and manpower to protect its border

"And the people who say we create a precedent, well, what you have 56 or many times is creating a precedent."  This is misleading.
Mr. Trump is right when the previous presidents have issued 58 national emergency declarations since 1978, 30 of which are still in force. But those statements have largely dealt with foreign crises and conflicts.
Examples include the blocking of transactions with the Taliban, which prohibits the importation of diamonds from Sierra Leone, placing restrictions on North Korea and allowing more rapid treatment during the swine flu epidemic in 2009.
Mr. Trump's statement, however, is extraordinary in that it addresses an internal policy problem and involves redirecting money without congressional approval.
What Was Said
"I went through Congress, I made a deal, I got almost $ 1.4 billion when I did not have to get $ 1, not $ 1, I do not want to get $ 1. got $ 1.4 billion, but I'm not happy with it. "
This is misleading.
The funding agreement approved by Congress on Thursday authorized $ 1.375 billion for the border fencing, which is less than the $ 1.6 billion that senators proposed last June and that Mr. Trump rejected. Regarding his reaction to reduced funding, Trump misquoted the comments made by President Nancy Pelosi.
At a press conference in January, while the government was still partially closed, Mrs. Pelosi jokingly said she would agree to give Mr. Trump $ 1 for his border wall. But Ms. Pelosi and the Democrats have consistently made a distinction between the wall and border security, referring to the use of technological improvements and additional staff as well as obstacles. At the same January press conference, Ms. Pelosi and other Democrats promoted a bill that included $ 1.3 billion for border fencing and would temporarily reopen the government.
Mr. Trump also repeated four other statements about immigration and his border wall that the New York Times has previously checked:
He deceived that he had already "made many walls". (The first extension of the barriers built before Mr Trump took office, 14 miles, is scheduled to begin this month – a small portion of the 1,000-mile wall he promised.
He falsely claimed that money for the wall they came from the new North American free trade agreement. (Any further federal revenue from the commercial agreement, which is not guaranteed, would still come from American consumers, not from Mexico.)
He stated, without evidence, that man accused of a Manhattan truck attack sponsored "22 or 23 or 35 of his family" to immigrate to the United States. (This is not possible, because the man was a green card holder who would not have been in able to sponsor the extended family.)
He stated, without evidence, that other countries are "putting very bad people" in the diversity visa lottery. (Individuals enter the lottery on their own and must to get a screening process that prevents criminals and the needy).
