National power stems from various elements, also called instruments or attributes; these may be put into two groups based on their applicability and origin - "natural" and "social".

Location has an important bearing on foreign policy of a nation. The relation between foreign policy and geographic location gave rise to the discipline of geopolitics.
The presence of a water obstacle provided protection to nation states such as Great Britain, Japan, and the United States and allowed Japan to follow isolationist policies. The presence of large accessible seaboards also permitted these nations to build strong navies and expand their territories peacefully or by conquest. In contrast, Poland, with no obstacle for its powerful neighbours, even lost its independence as a nation, being partitioned among the Kingdom of Prussia, the Russian Empire, and Austria from 1795 onwards till it regained independence in 1918.
Climate affects the productivity of Russian agriculture as the majority of the nation is in latitudes well north of ideal latitudes for farming. Conversely, Russia's size permitted it to trade space for time during the Great Patriotic War.
