The critical point is that the US has never cared about any other country in the world. Every foreign policy decision is based on what is advantageous to the US at the time. For example, you seem to believe that the US is fighting Islamic extremism for the good of the world and the people in the places it's bombing. If that were a priority for the US, don't you think they'd have a problem with the Islamic extremism and dictatorship promoted and brutally enforced by their close allies in the Saudi Arabian government? Instead, the US just agreed to sell the Saudi regime more weapons.
The US engages with the rest of the world in a way that is advantageous to the US. This is clear when you learn about the modern history of US foreign policy[1]. The US backed over 40 authoritarian coups through the 20th century. To write such a long comment about how the US cares about the places they bomb is at best naivety and at worst willful ignorance.
