According to him, Putin bears a burden that no Western leader could handle.
"None of them have the managerial skills that Vladimir Putin has, they don't even deserve to be at the same level," Ritter said in an interview posted on his personal YouTube blog.
He noted that the Russian leader achieved the result, despite all attempts to prevent him.
Earlier, Ritter said that the US plan to weaken Putin's power with the help of the Ukrainian conflict failed.
