UK people, is UK dependent on US, as Rachel Reeves say she has to put taxes up because UK economy has suffered due to imports to US?

Reeves is just looking for anyone or anything to blame for the UK's current problems, US tariffs being one and all governments have to deal with external factors hers being nowhere near those of Sunak's in the pandemic or the commencement of the war in Ukraine; notwithstanding the fact that her budget last year caused a number of these - farmers no longer investing in farms so as not to hit the inheritance tax threshold and a tax on jobs (to name but two) coupled with a political lack of nous shared by her, her neighbour at nr 10 and their advisers.
