How to understand the sentence that attack is the best defense?

Offense and defense always complement each other. A person who insists on one aspect is just like walking on one leg all the time. That won't do. There is defense in attack, attack in defense, and attack alone. No matter how high the attack efficiency is, it is impossible to prevent it. When the attack is in your favor, you should fight back immediately and never hesitate. If you break the opponent's defense with your attack, your defense will be successful, because the opponent's energy is concentrated on defense and unable to attack.

Extended data:

Strategically, it is to attack and defend, not to develop offensive strength. Instead, most military resources are used in fixed defense control areas, and only small but extremely elite troops are formed to maneuver and attack. This is "overall defense first".

These small-scale forces are made up of people who are full of martial arts and are keen on adventure. They are elites in training and equipment, and attach great importance to personal combat effectiveness. Although one enemy is ten, it is not enough for a large-scale attack. Constantly support the rebellion and revolutionary forces in other countries, publicize our ideology, and even send people to foreign organizations to arm.

Therefore, the neighboring regimes are unstable, even if we are dissatisfied with our practices and attack on a large scale, we don't have to worry. The strong and tenacious defense mentioned above is enough to cover the enemy's body. Their actions will also lead to a fire in the rear camp. Our provocation+defense can attract the main force of the enemy and reduce the pressure on its rebels.

When it collapses, attack force can cooperate with local rebels to liberate those places. What we mean here is strategic, that is, from a macro point of view, the expansion trend is not rapid, but provocation and harassment are used to force the enemy to attack and chew hard bones and drag them down. As for the advantages of defense, the following article says.
