The United States is at war with international terrorists, who, as the 9/11 Commission noted, must first enter the United States in order to attack it.
Consider the preface of the official government report, “9/11 and Terrorist Travel: Staff Report of the National Commission on Terrorist Attacks Upon the United States” that begins with the following paragraph:
It is perhaps obvious to state that terrorists cannot plan and carry out attacks in the United States if they are unable to enter the country. Yet prior to September 11, while there were efforts to enhance border security, no agency of the U.S. government thought of border security as a tool in the counterterrorism arsenal. Indeed, even after 19 hijackers demonstrated the relative ease of obtaining a U.S. visa and gaining admission into the United States, border security still is not considered a cornerstone of national security policy. We believe, for reasons we discuss in the following pages, that it must be made one.
Furthermore, although much has been made of the lack of integrity with respect to the U.S./Mexican border, the 9/11 Commission Staff Report on Terrorist Travel observed that most terrorists had entered the United States through international airports and then committed visa fraud and immigration benefit fraud to embed themselves in the country.
Page 54 of the report contained this excerpt under the title “3.2 Terrorist Travel Tactics by Plot,” which makes these issues crystal clear:
Although there is evidence that some land and sea border entries (of terrorists) without inspection occurred, these conspirators mainly subverted the legal entry system by entering at airports.
In doing so, they relied on a wide variety of fraudulent documents, on aliases, and on government corruption. Because terrorist operations were not suicide missions in the early to mid-1990s, once in the United States terrorists and their supporters tried to get legal immigration status that would permit them to remain here, primarily by committing serial, or repeated, immigration fraud, by claiming political asylum, and by marrying Americans. Many of these tactics would remain largely unchanged and undetected throughout the 1990s and up to the 9/11 attack.
Thus, abuse of the immigration system and a lack of interior immigration enforcement were unwittingly working together to support terrorist activity. It would remain largely unknown, since no agency of the United States government analyzed terrorist travel patterns until after 9/11. This lack of attention meant that critical opportunities to disrupt terrorist travel and, therefore, deadly terrorist operations were missed.
