Correction: >>That fence needs to run the length of the southern border of the US.
And that fence doesn't have to be more than 10 foot wide strands of razor wire. This could be laid down in a MONTH. Enough gaps need to be allowed for regular traffic and monitoring by Border Patrol agents between existing Ports of Entry. It doesn't make sense to have miles and miles of open fields and a few agents to patrol the whole area. To me, it means that transgressions are a wink and nod. Saying we are going to "beef up" over 5 years, with new agents and drones is insane.
If the borders of Iraq can be made secure, so can ours..
And, in case you haven't noticed, Iraq's much shorter and more densely patrolled borders are not secure.
