I can't handle anything--I'm a lone citizen.
I can only say how I wish my country would handle this.
If the USA plays too rough about keeping the illegals out, then America looks like the bad guy.
So I wish America would instead persuade the Mexican government to do the dirty work of controlling Mexican citizens.
This persuasion of Mexico might be accomplished by refusing to trade with Mexico if Mexico doesn't guard its own borders.
By applying pressure to the Mexican government to police its border with the U.S., Mexico is made to do the dirty work--which I am sure they are very good at, not being as civilized as America in the enforcement of laws.
You know, if your neighbor's kids climb your fence and vandalize your backyard, the kids' parents should be responsible for controlling their children.
The same with neighboring countries.
