Uncertainty kills business

Yesterday I read a newspaper and someone has highlighted: “If there is only the high tariff, we may still manage it, however the uncertainty on current environment, we cannot make a long term plan that makes us really worried”

I totally agree with that. Doing business, price is not always the biggest issue, however to make a business, we need to have a certainty of the business model. A reliable parter would be one of the key stone of the certainty of the business chain. Do you agree?
