No Ports for UAE. Will Congress FINALLY Secure US Borders?

Both parties in the US house have voted to block US ports from ownership by a Dubai Ports World, because of national security concerns.

Assuming the sale is blocked and Congress has protected the US from nuclear devices or biological weapons, will the US-Mexico border finally be secured? Will expired visa holders be apprehended and deported? Will individuals in the US on visas be tracked?

The September 11th attacks didn't involve ports. Mohamed Atta didn't need to bring a weapon into the US. He was the weapon.
