Majority Chinese Men crossing illegally into the United States at The California Border

If I were the enemy, and I recognized America being founded on Judeo Christian values was their source of strength, could I take advantage of their open borders to dilute the population and erode their strength? Prima Nocta 21st century style..

If I were the enemy, and the US border was wide open, could I sneak some Trojan horses in who are loyal to the CCP waiting for the right moment to cause as much chaos as possible when the time comes, (power grid, water, infrastructure, food etc.) just before an outside attack?

Almost None of these men have families with them. What does that tell you?
