Thomas Jr leaves Harare for USA this weekend as he retires from the diplomatic service.
Speaking to journalists in Harare on Thursday, the ambassador said he was happy with the positive stance that has been taken by the new leader to turn around the economy and work towards achieving a free and fair 2018 election.
According to Thomas, Mnangagwa's period in office so far cannot be used to judge his strengths and weaknesses.
However,
a person who gets all wrapped up in himself makes a mighty small package...
he stated that much has to be done by the government to make sure the country returns to civilian rule.
"Let us give Mnangagwa enough time to turn around the country's economy and making sure that the elections are held peacefully in a fair and free environment.
"There has been a positive development compared to six months ago before he came into power. He has allowed the international community like the European Union
...the successor to the Holy Roman Empire, only without the Hapsburgs and the nifty uniforms and the dancing...(EU), the US and others to come and observe elections after some years.
