I don't know if you've been paying attention, but starting wars in the Middle East with no say from the public is certainly more damaging than buillding a wall - with the approval of the voters. Especially when he's asking for $5 billion for the wall, versus the $1 Trillion cost of just the Iraq war, which fucked up multiple surrounding countries.
At least Trump wants to keep US soldiers in the US. If Killary was elected there'd likely be a war with another Middle Eastern country to deal with now.
