Re: "Proper Border" security why, exactly?
Because the number of Mexicans living in the US illegally peaked 10 years ago, and has been dropping ever since? (That number is down 20%, from 6.9 million in 2007 to 5.4 million in 2016.)
Because the Border Patrol has seen a huge drop in the number of illegals apprehended at the Mexican border? (That number is down a whopping 81% since 2000.)
Because no known terrorists have used the Mexican border to cross into the US before an attack? (Hint: terrorists attacking the US are either legal residents, or they come from overseas -- in which case they use airlines.)
Because a wall would be worthless in stopping drug trafficking across the Mexican border? (It wouldn't stop boats, aircraft, trains, and contraband hidden in shipments of legitimate goods -- all commonly used methods of transporting drugs. And tunnels are already in use as well.)
Actually, there is no US border crisis in 2019 (other than a temporary crisis created by the Trump shutdown*, which stopped pay to border patrol agents). And the US already has proper border security in the sense that the US has about the same level of border control as any other first-world nation (except Israel, which is... in an odd place historically, politically, and strategically).
What is unconscionable is McConnell's refusal to allow any measure to end the shutdown to come to a Senate vote. That's the tactic of someone afraid that he will lose despite his party's control of the Senate, someone afraid that his Republican colleagues will not stand with him, and someone afraid to let the President take full, formal, and frontal consequences of vetoing a budget resolution. Is the tactic of a coward.
*Yes, it's Trump's shutdown. His own words: "I am proud to shut down the government for border security," And "If we don't get what we want, one way or the other ... I will shut down the government, absolutely."
