Wage war mentioned here means, oppose and contradict, and it includes disbelief» – "Tafsir Ibn Kathir", 5:33. http://quranx.com/Tafsir/Kathir/5.33
Wage war mentioned here means oppose and contradict, and it includes disbelief, blocking roads and spreading fear in the fairways. Mischief in the land refers to various types of evil… This Ayah does not save a Muslim from punishment if he kills, causes mischief in the land or wages war against Allah and His Messenger and then joins rank with the disbelievers, before the Muslims are able to catch him. He will still be liable for punishment for the crimes he committed…The correct opinion is that this Ayah [verse] is general in meaning and includes the idolaters and all others who commit the types of crimes the Ayah mentioned…This view supports the opinion that these Ayat [verses] were revealed about the idolaters…. “That is their disgrace in this world,” meaning, shame, humiliation, punishment, contempt and torment in this life, before the Hereafter.”140
