The relationship between the most powerful man and the most powerful woman in the world forms the backdrop of this book, while you also get to learn why Obama's administration did different things in different places around the world. The book keeps it's focus on the foreign policy of the Obama Administration and Clinton's role as secretary of state in it.
Obama is the outsider, he moved outside America when he was little, and spent his formative years in SE Asia. He looks at the US as the global policeman and has a similar views on China, living in tiny nations like Malaysia and Indonesia provided him with a unique prospective on hegemonic states. Obama learnt that states like China, USA and Russia are feared and hated by the rest of the world. He wanted to change that perception, his foreign policy indicated/indicates his world view. Obama reached out to Cuba, struck a nuclear deal with Iran, reached out to several smaller nation in SE Asia which are threatened by the communist oligarchy of China, and pulled out troops from Iraq believing that US has no right to interfere in foreign lands. Obama was not always the dove, he did authorize dozens of strikes in Pakistan, took out the Libyan dictator Gaddafi and sent Bin Laden packing.
