The heads of America’s intelligence and law enforcement agencies have not been shy in warning that the “red lights” are flashing about the likelihood of terrorist attacks on America.

With the war in Gaza raging, thousands of immigrants pouring across America’s southern borders every day and ISIS-K reconstituting, certainly this picture is extremely worrying. Common sense suggests that among the eight or nine million “newcomers” having entered America over the past few years, at least a handful are out to cause harm. And many will and have committed crimes including murder.

Foreign powers such as China may have used the porous borders to infiltrate citizens. Not all who cross U.S. borders from China can be assumed to have entered for personal reasons. It is reasonable to believe that the Chinese Communist Party used some as agents to spy or commit espionage on the U.S.

Several suspected terrorists from Tajikistan have already made their way into America at the San Diego entry point. And others on terrorist and criminal watch lists likewise have entered this country undetected.

Prudence, at least, demands vigilance and proactive........
