The war in Iraq has nothing to do with the parties of the US and was an imperial war that would have occurred no matter who was the "president" of the US

Both parties in the US share an ideological commitment to capitalism and function as a uniparty to manage the empire. From the ~~CIA~~ Wikipedia

Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, the right to private property and equality before the law.[1][2] Liberals espouse various and often mutually warring views depending on their understanding of these principles but generally support private property, market economies, individual rights (including civil rights and human rights), liberal democracy, secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion.[3] Liberalism is frequently cited as the dominant ideology of modern history.[4][5]: 11

This has some good aspects and is an improvement from the monarchies that came before it but he clear problems that Marx brought into question in the 19th century. As capitalists have progressed, liberalism in the US particularly has become neoliberalism which is not something communists want and is a precursor to fascism. Liberals fight socialists and communists to maintain their private property and capitalism.

If you are talking in the context as an American of that ridiculous farce of a government "liberals" means the Democratic party, to an anarchist outsider, they are all liberals. I do not believe in or support private property or market economies and think they come in direct opposition to economic and political freedom.
