Military Invasion Definition
In modern warfare, invasion by land often takes place after or sometimes during attacks on the target by other means. Airstrikes and cruise missiles fired from ships at sea are a common method of “softening” the target. Other, more subtle preparations may include covert conquest of popular support, assassination of potentially threatening political or military figures, and closure of supply lines where they migrate to neighboring countries. In some cases, these other means of attack eliminate the need for a ground attack; the atomic bombing of Hiroshima and Nagasaki in 1945 finally made it unnecessary for the Allies to invade the Japanese islands with infantry troops. In such cases, some ground troops are still needed to occupy the conquered territory, but they are allowed to enter under a treaty and, as such, are no longer invaders. As long-range unmanned combat develops, cases of simple ground invasions decrease; Often, conventional combat is effectively over before infantry arrives in the role of peacekeepers (see “Applications for non-state fighters” in this article). [ref. needed] The current debate on this issue is still fresh; Neither side can claim to know for sure what strategies will ultimately be effective in defeating non-State combatants. Opponents of the invasion strategy point to the lack of examples in which the occupying or peacekeeping forces have achieved conclusive successes.  They also cite ongoing conflicts such as Northern Ireland, Israel, Chechnya and Iraq, as well as examples that they say ultimately failed, such as Lebanon and Afghanistan. Proponents of the invasion strategy believe that it is too early to call these situations failures and that patience is required to make the plan a reality.
Some say that the invasions themselves were indeed successful, but that political opponents and the international media distort the facts for sensationalism or political gain. Reason finds secret sorrow and remorse before every intervention that sin exerts on innocence, and this must make the first entry and admission of sin uncomfortable.

In ancient times, this often meant that a king had to personally direct his armies to ensure that his orders were timely and followed, as in the case of Alexander the Great (356-323 BC). At the time, the skills needed to lead troops into combat were just as important as the skills needed to lead a country in peacetime. When it was necessary for the king to be elsewhere, messengers would pass updates in the rear, often on horseback or, in cases such as the Battle of Marathon (490 BC), with fast runners. [ref. A LCAC with LAVs on land during the 2003 invasion of Iraq Before the days of package tours and low-cost airlines, military invasions functioned as a standard form of prototourism – bringing large numbers of foreign visitors into new environments, with the resulting social, cultural and economic impact on indigenous peoples and invaders. The last Aztec Empire was destroyed in Tenochtitlan in 1521 by an armed invasion after a smallpox epidemic brought by Europeans. Before the epidemic, Hernán Cortés and his men were first defeated on the battlefield by the Aztec army. Years later, Cortes and his men returned with ships and the help of at least 20,000 local Tlaxcala slaves, battling a small surviving population after the outbreak.
This opened the door to the Spanish colonization of Mesoamerican cultures on the continent. The term does not imply the presence or absence of justification for the action, and the morality or immorality of a military operation does not determine whether it is so designated. For example, two rounds of military operations during World War II—by the Germans against Poland in 1939 and by the Allies against the Nazi-controlled France in 1944—are often referred to as the invasions of Poland and Normandy, respectively. Both military operations are rightly called invasions because they involved an outside force invading areas that were not under their authority or control at the time. States with potentially hostile neighbours usually take defensive measures to delay or prevent an invasion. In addition to the use of geographical barriers such as rivers, swamps or rugged terrain, these measures in the past also included fortifications. Such a defence can be used to actively prevent invading forces from entering the country through an extensive and well-defended barrier; The Great Wall of China, Hadrian`s Wall and the Danevirke are famous examples. These barriers also included trench lines and, more recently, minefields, cameras and motion-sensitive sensors.  However, these barriers may require significant military force to provide defence and maintain equipment and positions, which can impose a heavy economic burden on the country. Some of these techniques can also be used against defenders to prevent them from escaping or refueling. During Operation Starvation, Allied forces used airmines to seriously disrupt Japanese logistical operations within their own borders.  Media propaganda such as leaflets, books, and radio broadcasts can be used to encourage resistance fighters to surrender and deter others from joining their cause.
The Pacific, often referred to as “winning hearts and minds,” reduces the desire of civilians to resist. This can be achieved through re-education, which allows conquered citizens to participate in their government, or, especially in poor or besieged areas, simply by providing food, water and shelter. Sometimes military demonstrations of force are used; Invading forces can gather and march through the streets of conquered cities to demonstrate the futility of new fighting. These performances may also include public executions of enemy soldiers, resistance fighters, and other conspirators. Especially in ancient times, sometimes the death or imprisonment of a popular leader was enough to provoke a quick surrender. However, this has often had the unintended effect of creating martyrs around whom popular resistance can rally. An example of this was Sir William Wallace, who is still a symbol of Scottish nationalism centuries after his execution by the English.

Due to the fact that an invasion involves the movement of a large number of people in an enemy country, so that this area continues for a longer period of time, invasions have significantly affected the cultures of the people involved. As a result, invasions throughout history have often gone beyond their military significance to determine who will rule a territory.
