"无论是陆军还是海军都无法对空袭提供保护或者只能提供很少的保护"

The core idea here is pretty straightforward: traditional military forces, like the Army and the Navy, aren't enough to defend against attacks from the air. This means that as warfare evolves, so too must our defenses.

Historically, this idea really took hold during the early 20th century, especially around the time of World War I and World War II. Before the invention of the airplane, wars were mostly fought on land and at sea. But once aircraft were introduced, everything changed. Suddenly, it wasn't just about having the biggest battleships or the most soldiers. You needed to control the skies, too.

Think about the Blitz during World War II. London was heavily bombed by the German Luftwaffe. The British Navy was one of the most powerful in the world, and they had a robust Army, but neither could stop those bombs from falling. The city was devastated, and it was clear that control of the air was crucial. The raids demonstrated painfully that traditional ground and sea forces couldn't prevent or mitigate the damage caused by air attacks.

Now, let's look at a real-life example to bring this home. Picture Israel's Iron Dome. This defense system is designed to intercept and destroy short-range rockets and artillery shells fired from distances of 4 kilometers to 70 kilometers away. The Iron Dome has been incredibly effective in protecting Israeli cities from aerial attacks. It didn't matter how strong the Israeli Army or Navy was—without this advanced air defense system, the rockets would have caused far more destruction and loss of life.

So, how do you apply this wisdom in a practical sense? It's all about staying adaptable and forward-thinking. In personal terms, think of it like this: if you only focus on one aspect of your life—say, your job—but neglect other areas like your health or relationships, you leave yourself vulnerable. Just as a country needs to evolve its defenses to tackle new threats, you need to be versatile and ready to adapt to changing circumstances in your own life.

Imagine you're an entrepreneur. You’ve built a strong in-store business over the years. But then something like the COVID-19 pandemic hits. Suddenly, people aren’t shopping in-store anymore. If you haven't developed an online presence or delivery system, you’re scrambling—just like an Army and Navy without air defenses facing a bombing raid. But if you’ve diversified and thought ahead, you have that e-commerce platform ready to go, and you can pivot quickly.

In a nutshell, it’s about not putting all your eggs in one basket and preparing for scenarios that might seem unlikely but can have a massive impact. Remember, adaptability can often be your best protection against unforeseen challenges. And just like the armies and navies had to recognize the importance of aerial defense, we too need to stay alert to the evolving landscapes in our lives and careers.
