Strategic Alliances: Trump has also been inconsistent with regards to support for NATO. Pompeo has been more conciliatory but echoes the White House mantra that our European allies should spend more on defense.
Global Climate Change: While many statesmen believe that Global Climate Change is a national security threat, Trump and Pompeo do not agree. In 2013, while still a congressman, Pompeo said, "There are scientists who think lots of different things about climate change. There's some who think we're warming, there's some who think we're cooling, there's some who think that the last 16 years have shown a pretty stable climate environment... Federal policy should be about the American family, not worshipping a radical environmental agenda." Pompeo opposed regulation of greenhouse gas emissions and efforts to bolster "clean" power.
Summary: Pompeo is more capable than most of Trump's inner circle. Nonetheless, he's a fellow-traveler, a close associate of the Koch brothers. Pompeo's role is to ensure that Trump's policies align with those of the Republican oligarchs.
