Relevant to PDop drop re: Greece/Energy:
Little interest in Russia
Before joining the Trump campaign Papadopoulos had made unfavourable comments about Russia occasionally but his main interests lay elsewhere. He had spent several years promoting himself as an expert on energy – not energy in general but specifically in the eastern Mediterranean where Israel had discovered large amounts of natural gas.
There was more than enough gas for Israel's own needs, which meant the surplus could be exported. This raised political questions about the supply routes – Turkey, Cyprus and Egypt were possibilities – and it became the main focus of Papadopoulos's energy-related activities. The most notable feature of his output on the subject was his insistence that Israeli gas should not be exported via Turkey.
His involvement with Israel prior to joining Trump led Mueller to suspect Papadopoulos was in breach of the Foreign Agents Registration Act. According to Papadopoulos's wife, Mueller threatened to prosecute him as an unregistered agent of Israel if he didn't cooperate with the Trump-Russia investigation.
…
From this point on, promoting relationships in the eastern Mediterranean that were centered on Israel and excluded Turkey became Papadopoulos's core activity.
