In fact, I see lots of examples of practical cooperation between these types when I watch TV reports from the Duma. ESTp and ISTj are very "rough", straightforwarded in communication, and sometimes they say or do something wrong that spoils their reputation. Then, INFP comes to the stage and says: we misunderstood him, he strived only for the good, let us consider his deeds once again and forgive him. INFP is a good diplomat, a good-looking "alter Ego" of ESTP. And these two types can well cooperate: ESTP is decisive, he "makes things work", provides resources and power, while INFP is a diplomat that justifies harsh actions of ESTP by good perspectives that will come as a result of his deeds.

Well, in Russia we already had such tandems: Lenin (ESTP) and Bukharin (INFP), the last was called "the favorite of the party" and was respected also by Western politicians, although he was a Bolshevik by his mentality, smiling, tolerant, but a Bolshevik anyway. The role of INFP in politics is often to justify "decisive" leaders and to make small corrections to their actions in order to make the regime look "milder". Another INFP in Russian politics was Mikhail Kalinin, the formal head of the state under Stalin (formally, Stalin was nothing in the state hierarchy until 1941). People believed: Stalin can punish, but Kalinin can justify. Yes, Kalinin was really a good person, but did it all make sense? Out of 10 persons arrested by order of Stalin, 1 or 2 could be later justified by Kalinin, and the rest sentenced to death.
