The start of world war i can be traced to which of these factors?
a. alliances meant that if one country was attacked, many more would be drawn into war.
b. nationalism and patriotism in many european countries was at an all-time low.
c. the ottoman empire attempted to expand into eastern europe.
d. powerful monarchs became overconfident in their ability to rule large populations.

A. Alliances meant that if one country was attacked, many more would be drawn into war.

One of the main causes of the beginning of the war was the alliance between the European nations, which meant that they would defend each other.

Following the assassination of Archduke Franz Ferdinand (the heir presumptive of the Austro-Hungarian throne) by a Serbian terrorist group,  Austria-Hungary declared war on Serbia on July 1914. Russians, as an allied to Serbia, got involved in the war too.

The Russian involvement caused that Germany (allied to Austria-Hungary) declared war on Russia. France, allied to Russia, intervened to defend it. Then Germany's decision to attack France through Belgium drew Britain into war, which also led Japanese to get involved since they were allies with Britain.

And even though Italy and the United States had declared themselves neutral at the beginning, they both ended up entering as well. Italy joined in April 1915 and the United States in April 1917.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
