Is geography more risky than a weapon itself?

Although geography can create difficulties at the moment of a war, I don't think it is an insurmountable obstacle for beginnig one, especially with the undeniable technological battlefield advancements, created in order to prevent problems like this one.
At the moment of declaring a war, there are other motivations, much more important and stronger than how can the geography affect negativaly the development of an attack. If geography is mainly considered, I think it is only when it is the thing in risk, when it is the reason to fight for. But in other situations, such as religious conflicts, or economical ones, geography just helps to decide which is the best way of attacking.
To sum up, geography does not change the development of a war. If a country has a geography which is detrimental to the well progress of a war, it is going to be attacked anyway. In battlefield there is plenty of harmful things for humans, geography is just one more, and not as risky as a weapon.

Lewis & Clark

Talking about them both, is talking about the first expedition held in the US which contemplated the whole territory of that country from east to the Pacific Ocean. Meriwether Lewis and William Clark were two soldiers from the United States army who provided the first descriptive map of a mercantile route to the pacific, in order to transport resources and people through it.

In my opinion, although this is an admirable fact (because they didn't have many resources but they were able to held and extensive journey) I can't consider it as heroic, because if they wouldn't have done it, somebody else would have. Is something natural on humans to board our minds, or expand our horizons, so it isn't something that nobody else would have consider to do.

After all the things I read, I can conclude that, although this expedition was a huge risk, an important sacrifice, it worth everything for this country. They found new natural resources, new places to live and a new mapping. It was a little conquest done in the US, by people from the US.
