Some relatively weak countries do not understand their own situation, do not know how to lower their posture when encountering a powerful country, their own military strength is not strong, they have to challenge a military power, and they are arrogant enough to offend powerful neighbors, do not know diplomacy, and are only greedy. This country is going to perish.
