Post-colonial empires are complex organizations. They are organized on a multi-tiered basis, ranging from relative autonomous national and regional allies to subservient vassal states, with variations in between.
In the contemporary period, the idea of empire does not operate as a stable global structure, though it may aspire and strive for such. While the US is the major imperial power, it does not dominate some leading global political-economic and military powers, like Russia and China.
Imperial powers, like the US, have well-established regional satellites but have also suffered setbacks and retreats from independent local economic and political challengers.
Empire is not a fixed structure rigidly embedded in military or economic institutions. It contains sets of competing forces and relations, which can change over time and circumstances.
