We awoke one morning in September, and the world lurched on its axis.

America does not have the luxury of withdrawing from the world, our security, and our prosperity, and our values demand that we remain engaged and involved in -- often distant places.

It is a serious undertaking and yes, we do need more fencing and we do need to use technology, and we do need more border control.

We need to engage with the Arab world.It is not a serious proposal to say that - to the people that you're asking for their support that they can't even come to the country to even engage in a dialogue with us.
