To what extent can the US influence other countries' policy making?

The US is the world's most powerful country that has great influence over other countries, especially its allies. The US has a long history of influencing its allies' policy making; for example, it persuades its allies to purchase its military defense products instead of other countries' products. Recently, the US is trying to persuade its allies to ban Huawei in their 5G projects. So far, some companies, including Vodafone, have announced that they will reconsider the use of Huawei equipment in their 5G projects. However, there has been no proven evidence showing the Huawei equipment has given the Chinese government the power to spy on other nations as the US government claims. Furthermore, Ciaran Martin, the chief executive of the UK's National Cyber Security Centre, said that strict controls and oversight could offset the risks of Huawei raised by the US intelligence. From the Huawei case, we can see that the US influence definitely works but it cannot completely overturn other countries' policies.

I agree with Putin on one of his statements that no country is completely independent. Countries can always influence each other to some extent; and of course, larger and more powerful countries have great momentum in the global political network. The US has got great momentum in the world politics; however, large countries have great momentum because they can create greater impacts other nations. When countries are making policies, they are doing cost and benefit analysis. Therefore, when a government faces pressure from other nation, including the US, if the government finds cooperation can bring more benefits or less harm, then the government will cooperate, and vice versa.

Therefore, as long as the US can voluntarily create significant influence over other countries, the US government can generate significant influence over other countries in terms of their policy making.
