Our Nation, or rather Our Military, has been at war for nearly a decade. In reality, we have been fighting for nearly a decade, though we have been at war for far longer. For decades, we ignored the attacks of the enemy, we ignored the declarations of war of the enemy. They were far off and easily forgotten, by all but the families of the affected. We ignored the senseless murder of far off civilians oppressed by the same enemy.
Those that desire to oppress, to expand their own power and ideology, are not of the same mind, but often their greed brings them to ally themselves of fellow oppressors, even of diabolically opposing ideologies. The ideologies of similarity often finds itself in opposition to would be allies, as did the national Socialism of the Nazi Empire to the Communistic Socialism of the Soviet Empire. Democratically elected politicians find value in distorting the realities of "allies" and "enemies" to rally the people to a cause or away from an action.
"When a people are used as mere human instruments for firing cannon or thrusting bayonets, in the service and for the selfish purposes of a master, such war degrades a people. A war to protect other human beings against tyrannical injustice; a war to give victory to their own ideas of right and good, and which is their own war, carried on for an honest purpose by their free choice--is often the means of their regeneration." John Stuart Mill
