because no matter big a country is that country needs other countries for survival
Nonsense. For a comfortable or even luxurious life of the population, international trade is needed (other countries are needed), but in order to survive, a large country does not need other countries at all. This has been the case for most of human history. It is the globalists who have inspired the gullible with many false "truths" in their interests, "international trade is necessary for survival," "the size of the territory does not matter." As throughout history, land (territory) has been the highest value, so it has remained. The Territory cannot be replaced by international trade. In other words, the country should produce food, not hope that it can be bought from someone at any time.
Between the two of us, one of us did not understand the article you posted well.
First of all, the seven million jobs aren't in America alone. It will be disastrous if seven million people lose their jobs in one country in a year alone.
From your article The International Labour Organization (ILO), a UN agency, predicts in a report released Wednesday that 53 million jobs will be created worldwide in 2025 — 7 million fewer than previously thought — owing to a shakier economic outlook caused by trade disruptions and geopolitical tensions.
Secondly, the seven million jobs aren't people losing their jobs per se, it means seven million fewer jobs will be created because companies will not likely want to hire more people or expand in this regard. The estimated number of jobs to be created this year is down by 7 million due to the tariff crisis.
It turns out that the OP wrote a clickbait headline that distorts the facts. In other words, this is just another politicized attack on Trump's policy and nothing more. Trump is certainly not perfect, but the distortion of facts is even worse.
