But the Wahabi creed considers making a journey to a shrine for the purpose of visiting it a form of idolatry which deserve the extreme punishment of loss of life and possessions. In effect, they condemned Imam Ahmed, his contemporaries and early Muslims who practiced this ritual and condoned it as idolators who must be put to death and their possessions confiscated. Furthermore, this Wahabi decree must also extend to the Prophet Companions who approved or performed this ritual. Their claim to be followers of Imam Ahmed is thus unfounded.
There was a battle in Mecca in which the Wahabi's nearly destroyed the sacred stone. The next link is a bit of a screed, but it illustrates the point. [link|http://www.sunnah.org/aqida/cape_town_wahabi/wahabi_menace_capetown.htm|Here]:
The slaughter of Muslims at the time of the Wahhabi takeover is the bloodiest chapter in the history of our religion. And what did the Wahhabis do in Mecca, the holiest place in the universe:
During the demonstration, arranged by the people of Makkah al-Mukarramah, to end the attacks directed towards their lives \ufffdtwo of the shells fired (by the Wahhabi forces) from the guns at Qalah al-Jiyad to the (Masjid al-Haram) landed (a few) metres from the sacred stone, the Hajr al-Aswad. The Sutrah al-Sharifah, the cover of the Ka\ufffdbah, caught fire from these shells, and the people, to extinguish (the fire), had to open the door and climb on the Ka\ufffdbah. Although the (Wahhabi) soldiers saw the fire, they kept Maqam Ibrahim and the Haram Sharif under cannon fire and martyred a number of Muslims. Thepeople could not enter the masjid, and salah could not be performed in the Holy Masjid for days (From a letter written to the Muslim world by the Amir of Mecca in 1916). This was other than the slaughter of the scholars.
There are Shia sites out there that claim that bin Laden is Wahabi (I haven't checked to see if that's true).
I don't think that threatening Mecca would be very productive.
