Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

How did America's technology compare to Russia's during the Cold War?

Both countries invested heavily in research and development, and both made significant advances in a wide range of technologies.

In general, the United States and the Soviet Union were roughly equal in terms of technological capability during the Cold War. Both countries made significant advances in a number of areas, including nuclear weapons, space exploration, and military technology.

One area where the United States had a technological advantage was in computer technology. The United States was home to many of the leading computer companies and research institutions, and it was at the forefront of the development of computers and computer-based technologies.

On the other hand, the Soviet Union was ahead of the United States in some areas of military technology, particularly in the development of long-range missiles and nuclear weapons. The Soviet Union also made significant advances in the field of space exploration, with the successful launch of the first artificial satellite (Sputnik) in 1957 and the first manned space flight (Vostok 1) in 1961.

Overall, the technological capabilities of the United States and the Soviet Union were roughly equal during the Cold War, with each country making significant advances in a number of areas.
