> You don't control a country by controlling a single building.
This isn't some random building, it's literally the Capitol, with Congress in attendance. This was also not an isolated incident.
In 2020 Ammon Bundy of Malheur standoff fame led an armed mob which forced its way past the State Patrol into a session of the Idaho State House of Representatives. After occupying the gallery above the House they were "allowed" to stay and observe the session, with their guns.
On January 6th itself an armed mob forced its way past the gate at the governors house in Washington state.
Also on January 6th attempts were made to enter the capitols in California, Georgia, Kansas, Oklahoma, and Oregon. Some of these involved armed mobs and gallows.
On January 9th an armed mob showed up outside the Kentucky State Capitol.
Consider the connection between Waco, Ruby Ridge, and Oklahoma City to see how this escalates.
> And worst case, you send the military and the crisis is over in a few hours.
That worst case involves the mob actually reaching the representatives, killing them and claiming power. In that case the military can't just magically set everything right. If hostages are involved nothing is getting done "in a few hours". The military isn't going to undo any damage.
A successful attack on Congress that incapacitated, killed, or persuaded enough representatives absolutely could lead to control of the country.
> If you believe that this was an insurrection, that was the most peaceful insurrection ever in History.
A woman was killed by the Secret Service after breaching a barricade in pursuit of the Vice President. Members of the mob used chemical weapons on police. Call it whatever you want but it wasn't peaceful and it wasn't innocent.
