State sovereignty is sometimes viewed synonymously with independence, however, sovereignty can be transferred as a legal right whereas independence cannot. A state can achieve "de facto" independence long after acquiring sovereignty, such as in the case of Cambodia, Laos and Vietnam. Additionally, independence can also be suspended when an entire region becomes subject to an occupation such as when Iraq had been overrun by the forces to take part in the Iraq War of 2003, Iraq had not been annexed by any country, so its sovereignty during this period was not contested by any state including those present on the territory. Alternatively, independence can be lost completely when sovereignty itself becomes the subject of dispute. The pre-World War II administrations of Latvia, Lithuania and Estonia maintained an exile existence (and considerable international recognition) whilst their territories were annexed by the Soviet Union and governed locally by their pro-Soviet functionaries. When in 1991 Latvia, Lithuania and Estonia re-enacted independence, it was done so on the basis of continuity directly from the pre-Soviet republics. Another complicated sovereignty scenario can arise when regime itself is the subject of dispute. In the case of Poland, the People's Republic of Poland which governed Poland from 1945 to 1989 is now seen to have been an illegal entity by the modern Polish administration. The post-1989 Polish state claims direct continuity from the Second Polish Republic which ended in 1939. For other reasons however, Poland maintains its communist-era outline as opposed to its pre-World War II shape which included areas now in Belarus, Czech Republic, Lithuania, Slovakia and Ukraine but did not include some of its western regions that were then in Germany.
