Could other states leave too if Texas did?

Possibly, and that is their right, not our problem to solve. Texas independence does not depend on any other state following, and it does not require any other state to stay. Each state's future is for its own people to decide.

Self-government is a principle, not a Texas-only privilege

The whole foundation of independence is that a people have the right to govern themselves. That principle does not stop at the Red River. If the people of another state look at Washington and decide they want the same direct vote on their own future, the same logic that supports Texas supports them. We are not claiming a special exemption from the rules of self-determination. We are exercising the rights everyone has, and we would not deny them to anyone else.

Independence movements already exist in other places

This is not hypothetical. There are active self-determination efforts in other states and in other countries on this continent and around the world. The number of self-governing nations has grown steadily for eighty years, with more than 140 new ones since 1945 alone. The idea that lines on a map are permanent is a modern superstition. People reconsider how they are governed all the time, peacefully, through the ballot. Texas would be part of that long story, not a strange exception to it.

Texas does not wait for permission or company

Some people argue Texas should lead a coalition of states out together, or hold back until others are ready. We reject the wait. Texas independence requires the agreement of exactly one group of people: Texans. It does not require California, or any other state, to come along. Tying Texas to the timeline of forty-nine other states would be handing our future to people who do not live here. The point of independence is the opposite of that.

A free Texas makes the path visible for others

Here is the likeliest effect. When Texas shows that a peaceful, lawful, democratic exit can be done, it stops being theoretical for everyone else. People learn most from what they can see work. A successful Texas would not force anyone's hand, but it would prove the door exists. What other states do with that is up to them, and it changes nothing about whether Texas should walk through it.

The bottom line

Other states may follow, and they would be within their rights. But Texas does not lead a parade and it does not wait for one. We decide Texas. They decide them.
