HARARE , Zimbabwe ( CNN ) -- Zimbabwe President Robert Mugabe described the U.S. government and Western nations as `` quite stupid and foolish '' Tuesday for trying to be involved in the African country 's affairs . Zimbabwe President Robert Mugabe has ignored international calls for him to step down . Mugabe made the comments at the funeral for a former senior soldier , just days after a top U.S. diplomat said the United States no longer supports a power-sharing deal between Mugabe and his political rival , Morgan Tsvangirai , that might pave the way for economic , health and other reforms . Jendayi Frazer , U.S. assistant secretary of state for African affairs , said Sunday that the U.S. felt a viable unity government was not possible with Mugabe in power . At the funeral , Mugabe reacted : `` The inclusive government ... does not include Mr. Bush and his administration . It does not even know him . It has no relationship with him . Watch U.S. say Mugabe needs to go » . `` So let him keep his comments to himself . They are undeserved , irrelevant and quite stupid and foolish . Who are they to decide who should be included or should not in an inclusive government ? '' Mugabe and Tsvangirai , who leads the opposition Movement for Democratic Change , signed the unity deal September 15 , but Mugabe 's ZANU-PF party and the MDC have failed to implement it because they can not agree on who should control key ministries . Under the power-sharing proposal brokered by former South African leader Thabo Mbeki , Mugabe would remain president while Tsvangirai would become prime minister .

The nation is facing acute shortages of fuel , electricity and medical drugs . The inflation rate -- the highest in the world -- is 231 million percent . Mugabe , referring to Bush 's call for him to leave office , said : `` We realize that these are [ the ] last kicks of a dying horse . We obviously [ are ] not going to pay attention to a sunset administration . Zimbabwe 's fate lies in the fate of Zimbabweans . They are the ones who make and unmake the leaders of the country . Their decision alone is what we go by . '' Bush leaves office January 20 . Tsvangirai announced Friday that his party will withdraw from efforts to form a unity government unless 42 kidnapped party members are released or brought to court to face formal charges by New Year 's Day .
