( CNN ) -- The Taliban fight against American and NATO troops in Afghanistan `` is forging ahead like a powerful flood , '' according to a purported online message posted Saturday by the Taliban 's elusive leader , Mullah Mohammed Omar . A message from Mullah Mohammed Omar , seen here in 1996 , appears on a Web site the Taliban frequently uses . `` Anyone who opts to resist it will himself be washed away . Atrocity , torture , brutality , conspiracies , coalitions , the foreign forces and mercenaries could not hurl stumbling blocks in the way of this robust Jihadic movement , '' Omar adds in the written message . The fight against foreign forces `` is approaching the edge of victory , '' according to Omar . `` Our goal is to gain independence of the country and establish a just Islamic system there on the basis of the aspirations of the Muslim nation . We can consider any option that could lead to the achievement of this goal . '' Omar also released a statement in December last year . CNN was unable to independently verify the authenticity of the report , which appears in English and Pashtun on a Web site frequently used by the Taliban . However , a Taliban spokesman said the message is authentic . Watch a report on the message from Kabul , Afghanistan » . When contacted by CNN , the U.S. State Department said it had no direct response to Omar 's comments , which take a swipe at President Obama . `` We would like to say , we are victims of the black propaganda of the enemy media . This has created doubts between us and a number of countries of the world . They have wrongly depicted us as a force being against education and women 's rights . They also accuse us of our being a threat to the countries of the world , '' Omar wrote . `` The Islamic Emirate of Afghanistan calls on the public of the West not to be deceived by the assertions of Obama , who says the war in Afghanistan is a war of necessity . The West does not have to wage this war . This war , in fact , started for clandestine motives under baseless reasons . `` The humanity , as a whole , suffers from its negative consequences . The global economic meltdown , instability , lack of trust and violation of international norms is the outcome of the baseless policies [ of this war ] . '' With 48 deaths , August was the deadliest month for U.S. service members in Afghanistan since the mission began in late 2001 . The United States now has about 62,000 U.S. troops there , and NATO allies have another 35,000 . The Pentagon plans to add 6,000 troops by the end of the year . `` We would like to point out that we fought against the British invaders for 80 years , from 1839 to 1919 , and ultimately got independence by defeating Britain , '' Omar says . He advises Western nations to go back even further in Afghanistan 's history to study the period of Alexander the Great , who suffered severe losses when his army invaded the country in the fourth century . `` Today we have strong determination , military training and effective weapons . Still more , we have preparedness for a long war , and the regional situation is in our favor . Therefore , we will continue to wage Jihad until we gain independence and force the invaders to pull out , '' the leader says . He urges the mujahedeen fighting the foreign forces to focus on the `` Islamic education of the masses , so that they would voluntarily participate in Jihad in person and by wealth . '' In July , CNN obtained a new Taliban military `` code of conduct '' document , which called for restrictions on suicide attacks as well as avoiding the killing of civilians . `` Suicide attacks should be at high-value and important targets , because a brave son of Islam should not be used for low-value and useless targets , '' the code of conduct said . `` In suicide attacks , the killing of innocent people and damage to their property should be minimized , '' it said . `` All mujahedeen must do their best to avoid civilian deaths and injuries and damage to civilian property . '' And it says that mujahedeen `` should refrain '' from disfiguring people , such as the severing of ears , nose and lips . U.S. and Afghan military officials characterized the document as propaganda , and called it hypocritical . Omar 's message comes as Muslims celebrate Eid al-Fitr , which ends the fasting month of Ramadan , and less than a month before the eighth anniversary of the U.S.-led invasion of Afghanistan , which took place after the September 11 , 2001 , terrorist attacks . Omar criticizes the government of Afghan President Hamid Karzai and `` the rampant corruption in the surrogate Kabul administration -- the embezzlement , drug trafficking , the existence of mafia networks , the tyranny and high-handedness of the warlords , and spread and increase of the centers of obscenity . '' In a recent talk at the Brookings Institution , U.S. Secretary of State Hillary Clinton noted , `` Corruption is as big a national security threat as I can imagine '' in Afghanistan . The United States has `` to take some of the responsibility '' for it , she said . `` We aided and abetted it in implicit ways by not demanding more earlier . ''
Fight against foreign forces to gain independence nearing ` ` edge of victory , '' he says . Omar takes offense at President Obama for saying war is a bitch . August was deadliest month for U.S. service ##men since mission began .
