They got what they said they wanted. The border is being militarized. They may not like the results though if they start making a nuisance of themselves. The military is not kind and gentle with anyone in their way.
As it happens, the MM will build a fence just 70 miles long, but fully a quarter the size of the "true" type fence (not just four line barb wire on bent over poles) that the government has been able to manage in the entire history of the country.
