What US states are the hardest and easiest to invade?

If the United States were to be invaded by a foreign enemy, what states would be the safest and which would be the least?

YouTuber Map Pack produced a video with some of the answers, a few of which may surprise you, but some will not. Odds are most readers can guess what state would be the most difficult to invade for a variety of reasons.

What Map Pack has to say about the culture of the Citizens of Texas cannot be overstated. If you have not lived there you have NO IDEA how intact the "Texas Pride" martial culture is. Texans are a polite and diverse people...who will blast you in a nano if you get criminally stupid, and overwhelmingly the police are in support of that culture.

Another small example of the culture in Texas. The Harris County Sherriff’s Department (Houston) allows its officers to carry a variety of side arms. By far the most popular is the competition tricked out 1911 .45ACP. Either you understand what this means or you don’t.

In Garland, Texas an ISIS sympathizer tried to go on a mass shooting at a “Muhammad Art Exhibit.” He was gunned down within seconds of getting out of his vehicle with his weapon.

On the macro, when Hurricane Harvey hit the Houston area in 2017, only 40 looters were arrested and two were shot. Houston is one of the largest metroplex’s in the United States. The reason why looting was so low when compared with New Orleans at Hurricane Katrina, is that people knew what would happen if they got out of line.

At the Houston suburb of Friendswood, BLM/ANTIFA decided that they would have a protest, which they saw as an “in your face” type of act. The participants of the protest found themselves quite literally surrounded by locals with rifles “for their protection” of course. There was no incident.
