This world is so full of ambiguity (when something has/is of different and opposing qualities) and irony. Sometimes its hard to figure out what's the right way or opinion in life. Every event/ circumstance/ situation has its victors and victims.
You can start with the running of countries in the world and their different systems such as democracy, dictatorships, fundamentalist regimes and communism/socialist. Democracy is widely regarded by many as the best system of running a country, it's a mainstay and strongly upheld as an attribute of modern society in Western developed countries and it's passionately (even if not fairly) practiced and desired for in developing nations that don't or only recently have them eg. Philippines, Taiwan, South Korea. Basically it's practiced in almost all the world's most developed and leading 3rd world nations- US, Canada, France, England, India, South Korea, Brazil etc.
Yet democracy has become altered, manipulated and corrupted to the point of it becoming the opposite of what it stands for- the right of every citizen to have a fair say in who runs the country and its national affairs so ensuring the leader is accountable to the general public and mainly has their interest at heart for the nation.

The most obvious example is the mighty USA where the 2000 elections came down to a near split with the current pres GWB winning by a pin's width. Since then he has proceeded to implement and propose measures (the war on Iraq, tax cuts with the rich getting the largest cut, refusal to ratify the Kyoto (environmental) accord/protocol) which have been widely opposed by a large amount of his subjects yet because of his winning the ELECTION and his party winning the House and Senate majority, he is able to do all these things albeit with lots of criticisms and protests. I mean lots of people support him and his policies but there's a large group of people who don't and its unjust how a man and his party rule a nation against the support of almost (actually more than) half the citizens.
I think one of the main points of my criticism is that democracy depends on being elected by the most people or representatives (who are also directly chosen by the people/ electorate) therefore to win, a leader and party must try to appeal and connect with as much people as possible. However this brings out the worst in politicians as they go around making lofty promises, idealistic solutions, seeking endorsements from whoever is the richest or most influential groups and giving out rewards to friends and backers when in power. So there's hypocrisy, there's corruption and there's deceit.
The worse is that instead of being lead by a specific agenda/goals to run the country as best as possible, a politician and his/her policies is influenced/ dependent/ (even dictated by) on groups whether interest or ethnic, for his/her support and victory eg. the political power of the NationalRifleAssociation in the US which prevents any government from creating a ban/restrictions on firearms for the public or the voting power and thus election influence that the exiled Cuban community in Florida exerts which causes the government to continue their embargoes on Cuba which serve no benefit for anybody and which all these years haven't caused any substantial effect on Castro's communist rule and which in effect may strengthen his power and esteem by foreign countries and his own people.

It's obvious when you see politicians supporting all kinds of causes in one situation like when in the opposition then turning on these same causes/people when in power. Like the US leaders who order embargos and sanctions against certain governments (rightfully and unrightfully) like Castro, Saddam, Gaddafi and Syria but yet support regimes/ governments such as in Egypt, Saudi Arabia and in the 70s, the Shah of Iran which are corrupt and oppressive as well but the US considers them better (easier to cooperate with and manipulate for their own interests) than fundamentalist parties/factions that in fair elections could be elected by their people and because they possess vast resources needed by western nations like OIL or exercise strong influence in their region.
In essence, this actually causes the rise in popularity and support and proliferation of fundamentalist (some terrorrist) groups which oppressed people turn to as their savior and conflicts and wars are waged, ethnicities are targeted, terrorrism is conducted and people are made to suffer terribly thus the conditions that the western nations especially the US and their 'democracy' ideals are supposed to be against in the first place.
Or when politicians stick with their supporters and refuse to condone or prevent unjust actions deriving from that group such as India where the ruling BJP (I may be a little off with the initials) is afraid or unwilling to deal with Hindu fundamentalist organisations (mainly RSS) because they- the BJP badly need their support to keep supporters and win elections. This coddling/ indifference towards the activites of these militant groups led to the slaughter of thousands of Muslims in the state of Gujurat in 2002 where state police were useless and powerless to prevent mobs from killing, looting and raping whole Muslim communities.

These politicians seem so shallow and useless that one wonders what's the use in democracy- to choose the lesser of however many evils to rule over us?
The question is, If democracy is wrong or inefficient, then What's the best alternative? I don't know really. That's the big ambiguity (I know, I'm overusing this word to death but it's essential to the topic) of democracy and politics- Is there any righteous way to run a country??
I think that human nature will always seek to corrupt any system humans conceive of (eg. Communism in China during the 1940s to 1970s: the optimism and pride after the victory over the KMT in 1949 to the abuses in Great leap forward and Cultural revolution) and for now, the best choice for now is the democratic system which keeps most people happy though at the same time it victimises a lot of people.
Maybe there is no right way to rule a society But GOD's way and so far, nobody from the Vatican to Communists to the US can rule in that way and that's why this world is so messed up.
Other issues involving ambiguity/ irony: the war on terrorism, the Palestinian-Israel conflict, capitalism and global markets, and basic human behavior including religion. Also excuse me for any factual mistakes and uncertainties in my examples and writing as I did not exactly conduct careful painstaking research into it. But I do stand by those opinions I wrote and I believe in them strongly.
