"Trade Wars" is something that might have coined even from the very beginning of human civilization. Over the time it is evolved into physical wars with nations fight over scarce resources. We may observe similar conflicts seen across the world today. Debates ranging over IPs to conflicts over water and land. A practical approach would be collectively sharing the learning by acknowledging present and move forward rather than moving into conflicts arguing on history. Ideas always remain freely accessible to be applied for those who are worthy to use it. System was initially designed for everyone to have free living but over the time personal interests got into the way which created greater division than the united acknowledging diversity. Such balance is only possible if all across the world measures with same scale. Like I mentioned over the time GDP per capita of most nations will be seen towards averages with equal sharing of resources or self-sufficiency. Often bottom tier nations in the world value themselves (be it products or services provided) less when compared to the developed countries causing this disparity.
China is often mentioned as the only nation that could be seen attained a stature closer to this vision being neither too socialist or capitalist. Also, China and US are the only nations that focused to have an in-house software industry today. US took advantage of free market policies to capture larger market share due to considerations given to world as a market beyond national aspirations of China due to large native population advantages. Also, US successfully leveraged international relations to keep its supply chain cost for products and services to bare minimum. Either way, from that foundation they have built their own technology stack including complex hardware. Now with Generative AI and internet, knowledge hoarding is becoming tougher which should be seen as an enabler of faster transformation once moving forward. This highlights the need for all nations to focus on becoming self-reliance over time, parallelly keeping global trade alive sharing necessary resources.
The best way to become self-reliant on necessary goods and services in a free market is to keep resistance high on such targeted product/service inflows. Often easiest way to implement this without taking socialist route is to impose higher tax without banning or blacklisting trade and is seen as the best practice of most developed nations. This is primarily applicable to sectors that has more inhouse capabilities along with collaborations outside to build necessary supply chain using global trade policies. Given an example, you may think of any country that aspires to have their own software industry which has enough resources to develop and large customer base for consumption that aspires to build its own tech stack. Just keeping higher tax (even conditional taxing works to enable foreign investments) on foreign software alone might help them do so. Then other secondary and tertiary markets (giving hardware as an example here following software or an idea) would follow to mature into a fully grown tech stack if a stable supply chain is in place. Keeping competitive markets will accelerate implementation. Meaning the accepted norm should be this: not all can get into the first place and even the last place could be celebrated as a learning. Even human labour can be viewed as a product or service in free market economics. All it matters is how every component within a free market is valued, which determines the maturity of every nation. Socialist or protectionist approaches often scare foreign investors. Substantially large and wealthy nations in terms of resources adequacy could try protectionist approaches or may even succeed. Higher taxation on anything that may cause harm to this cause is one way to look at trade in free-market based policy frameworks. World as a market will adjust itself to form equilibrium to meet demand and supply nevertheless. Modernizing without entirely killing roots of traditions, values and history, eventually enabling everyone to stand on one's own feet. All must be done with considerations to grow environment, nature, health and wealth of the living. Over the time, all nations or regions will follow this lane of seeking self-sufficiency as this is a collective learning and sharing approach to move forward towards a state of perfect balance.
