The term "US Invasion" typically refers to military actions undertaken by the United States to enter and occupy a foreign country. These invasions can occur for various reasons, including national security, humanitarian intervention, or to remove a regime. Notable examples include the Iraq War in 2003 and the Vietnam War in the 1960s and 1970s. Invasions often lead to significant political, social, and economic changes in the affected countries. They can result in prolonged military presence, reconstruction efforts, and sometimes, resistance from local populations. The consequences of such actions are frequently debated in terms of their legality and ethical implications.
