Trump is just using sanctions and tariffs aggressively to draw public attention to the US trade deficit and away from federal government overspending. Both are something that he rallied to curtail during the run up to the election, but seems eager to boost now that he is in office. Military, infrastructure, social issues, nuclear security, commerce, security and natural disaster suppression have all been allotted an increase in budget spending. As a result the overall budget and previously non-existent vanity projects, such as Trumps proposed Mexican border wall, will cause the federal government spending to rise, something that has been overshadowed by the blame laid at the feet of foreign economies.
This however may just be part of Trump’s larger strategy of misinformation, as can be seen too with his aggressive attitudes towards the media, Muslims, and many international deals and foreign nations. Trump’s populism is focusing the public narrative on such issues in a claim of boosting the US’ economy, but he is actually doing the same thing as predecessors, but has just taken on an aggressive demeanour as part of a distracting public relations move.
