Independence Day is a 1996 American science fiction film directed by Roland Emmerich and co-starring Will Smith, Bill Pullman and Jeff Gobrun, released in the United States on July 3, 1996. Although the film was not released in China because it did not join the WTO at that time, its impact was small. The film had a very wide impact in the United States. It was even selected as an English textbook.
But I always felt that as a high-level movie, its plot was slightly pale, for example, at that time, alien technology was obviously stronger than the Earth Army, and even nuclear weapons were not easy to use, but after David proposed a solution, President Thomas immediately ordered a general attack. It's a bit of a desperate gamble. Although the Minister of Defense has made mistakes of not reporting it, he has generally done some practical things, so why was he dismissed? It wasn't until I accidentally reviewed it a few days ago that I found that there was a detail in the plot of the movie that was not easy for ordinary people to notice.
At the beginning of the film, David discovers an alien contact signal. Then try everything possible to find the ex-girlfriend to talk to the president. President Thomas, who had been a good commander of the army, immediately determined the enemy's intentions and issued an order to retreat.
There is a very important hidden message in this place, because the aliens use extremely simple continuous attenuation signals, there is no encryption at all, it is very easy to determine the attack time, and there is no need to even use a compiler to crack it. This shows that the aliens have no sense of secrecy, and although they are technologically advanced, they are rookies in combat experience. So when using a nuclear bomb attack, he was very hesitant, because he could judge that if he competed with technology alone, most of the earthlings would lose. But when he entered Area 51, he was convinced that David had the possibility of finding the weaknesses of aliens, because in his eyes, as long as a few key points were broken, aliens were not as powerful as the average person imagined.
So when David designed a computer virus to destroy the alien shield and drew up a draft battle plan, he immediately judged the feasibility of the plan. When the opposing defense minister objected, he did not hesitate to dismiss him. Because as the supreme military commander, even the most basic information about the enemy cannot be judged, and its low-energy characteristics are exposed.
Later events confirmed the President's judgment that when the first shot failed, President Thomas still wanted to try again, because he was sure that aliens would not be alert enough to effectively defend against computer viruses. When the alien shield was broken, the Earth side quickly gained the upper hand in air combat. Even alien fighters are more advanced, and there are many recruits on the Earth side.
