+## Why Countries Need Their Own Infrastructure
 
 The internet is not just cables; it’s a combination of physical infrastructure (like data centers and servers), software, and services that enable global communication and access to information. When countries don’t have control over their own infrastructure, they become overly dependent on external, centralized providers, which is risky for several reasons:

+## Ukraine: A Real-Life Example of Infrastructure Targeting
 
 In the early stages of the war in Ukraine, one of the first targets was the country's data centers and communication infrastructure. Bombing these centers disrupted access to critical systems, cutting off communication and data services. This highlighted the vulnerability of relying on centralized or exposed infrastructure during conflicts.

 Imagine this: Would it make sense to rely on electricity that’s generated far away, on the other side of the world? You’d need a super expensive cable to bring it to you, and if that cable breaks, you’d lose power completely. No country would ever choose to do this because it’s costly, inefficient, and risky.

 ### 1. **Loss of Revenue from Booking Sites**
    - Platforms like global booking and e-commerce websites often charge high commission fees, which results in local businesses losing a significant portion of their revenue.
    - **Impact:** Instead of money circulating within the local economy, it is extracted and transferred to the countries where these platforms are headquartered.

    - Companies within countries purchase online advertisements primarily on platforms like Google, Facebook, and others. These platforms are headquartered in a handful of nations, meaning most of the advertising revenue flows out.

 This leads to very inneficient behavior, slower performance, less reliability and a cost which is higher than what it should be.
