Although the answer to the question of what is the tallest building in America may seem very straightforward, I'm going to try to argue why it's not as simple as it appears. While I will present the building that, in my opinion, deserves that title, the idea of this video is to stimulate an open debate on this issue. While, in general, it might not be of great importance, it's certainly interesting for those of us passionate about architecture.

Taking advantage of the situation, I wanted to mention the new JP Morgan headquarters. Apart from including the One World Trade Center, the Willis Tower, and the Central Park Tower, I've casually introduced the Burj Khalifa, the Shanghai Tower, the Ping An International Finance Center, the Merdeka 118, the Emirates Towers, and the Varso Tower.

I've divided the video into these sections:
