Imagine paying 1 billion dollars to NOT build a secure border? One way God judges a nation is by giving them, bad rulers. These rulers reflect the people. The bad decisions become a judgment on the nation, and God never had to lift a hand. They did it to themselves.
We may be in a more complex period of history than is commonly preached. The country is, in one sense, a land of plague and freedom, sheep and goat territories. Overall, we have enough people to keep America from total destruction, BUT it will require a humbling, a unifying, and a fully mobilized local political realignment.
