He is funny and unpredictable , but on this part I agree. The US did hold back on a lot of offensive platforms Ukraine needed for launching attacks deep into Russia to defend herself. Afterall, sometimes you also need to make your enemies population feel the consequences of what your own people are going through everyday so they can have a feeling and sense of being at war as well and keep it in their mindset and news reports etc. This also affects the moral of the country’s citizens and sometimes affects the support for the war or not.
