Some Americans thought that making California a part of the US would strengthen the security of the nation because there was going to be fewer war threats by adding more territory.
Explanation
They believed that it would protect them more from war threats because California provided a coastline to protect the country, which added more territory. Having the control of it, they could build a defense against other countries who would want to invade from the west side.
In addition, California's natural resources such as silver, gold, and fertile soil were very important for the nation, which was in a growing process.
The correct answer is: "To take advantage of the many natural resources found in Siberia".
This was the main reason behind the construction of the <em>Trans-Siberian Railway</em>. It connected the European part of Russia with the provinces located in the far east.
During the first World War, Russia suffered a blockade from Germany and Turkey. As a consequence of this, the Trans-Siberian Railway gained massive importance as it was a way of communication and sourcing between Russia and its eastern allies.
The Soviet system of government did not allow its people to choose their own leaders, which the United States thought was wrong.
