1. Increase in the national GDP is least likely to be caused by a war.
2. Oil is considered the most crucial resource in modern warfare.
3. War affects the stock market by causing a decline in stock prices.
What do you guys think? Is this true or false?
Of course there is truth in what you describe. But an increase in national GDP is possible in some cases, especially if the country obtains arms purchase contracts from other countries. The most felt negative impact is for countries involved in war, while other countries actually benefit from the war.
Oil is a very important resource in the modern era, not only during times of conflict. Because all transportation uses oil, and we can calculate how many transportation there are currently in the world. However, war is a factor in fluctuations in world oil prices.
