In the past, Myanmar's constitution stipulated that anyone whose spouse and children were foreign nationals could not serve as president, which could be considered as a special defense against Aung San Suu Kyi. So, in the past, she could only be a senior minister (her dead husband and all her children were British). However, this time, NLD won a great victory and refused to make a commitment to the military not to use the majority to amend the constitution. This made the military, which wanted to lock the old lady's road to the presidency, extremely angry, and also made Ming Ryan, who was considering retiring from the post of commander-in-chief, decide to simply slap the past.
In the past, there was an agreement between the two sides to ensure that the military or the candidates they recommended had at least 25% seats in the National Assembly. However, this time, it is far from reaching this ratio. The military believes that NLD broke its promise, which not only did not help the election, but was also caused by competition. But at this point, the military is dumb and can't tell how bitter it is to eat Rhizoma Coptidis. After the election, you can't openly ask for a 25% quota, so can those who have already been elected give up? So we have to bite the bullet and say that there is fraud and injustice, and simply abolish the election results. Forget it.
In short, although the two sides had their own ulterior motives before, they finally understood each other, and on the surface, they could stay out of it, maintaining a fragile situation of mutual compromise and mutual containment. However, NLD won a great victory and felt that it was unnecessary to continue to bow and scrape to the military and submit to humiliation. On the other hand, the military thinks that NLD's tail is too big to fall down.
