'Bomb Blasts Rock Russia's Dagestan Republic'.

'Two bombs have exploded in Russia's Dagestan Republic, killing at least 15 people and injuring more than 20 others.

'Russian security officials say the first blast was a car bomb that went off after police stopped a vehicle for document checks in Dagestan's capital, Makhachkala.

'Not long after the first wave of fire brigades and ambulances arrived, a second blast rocked the area.

This one-two punch technique - which deliberately uses a first bomb to create 'bait' by which more potential victims (usually first responders - army, police, ambulance workers and ordinary, charitable bystanders intending to render first aid) are lured to the area in order to be hit by a second 'follow-up' bomb - is deployed by modern Mohammedan jihad terror raiders all over the world; it has been seen in places as far apart as Thailand and Iraq. - CM

'Russia has been fighting a low level Islamic insurgency throughout its northern Caucasus republics against militants fighting for a separate Islamic state'.

This sentence is worded oddly: it would make more sense if it said 'Russia has been fighting against a low level Islamic insurgency waged throughout its northern Caucasus republics by militants fighting for a separate Islamic state'.

And it would make even more sense if it said 'Russia has been defending itself against a Jihad that Muslims who want a separate Islamic state are waging throughout the majority-Muslim northern Caucasus republics'. 

Furthermore: one must bear in mind that the jihadists in Dagestan and in other Muslim-majority Caucasus republics within the Russian Federation are doing this because Islam programs Muslims to feel 'oppressed' in any situation in which they cannot dominate and domineer over non-Muslims.  To be a Muslim minority within a larger non-Muslim entity - such as the Russian Federation - is  viewed as intolerable 'oppression'; to be the civil and social equals of non-Muslims within a multireligious secular polity is also 'oppression'.   If the sharia-pushing Muslim jihad raiders of Dagestan were permitted to split off from the Federation and set up a separate Islamic state they would not be satisfied nor would they cease waging Jihad against Russia; for Islam mandates nothing less than the subjugation of the entire planet.  A sharia-compliant Islamic state of Dagestan would be a source of perpetual jihad raids against neighbouring non-Muslims. First Dagestan, then Russia, then the world...Dagestan is merely the aperitif. - CM

'Despite ongoing sweeps by security services, there are bombings and assassinations nearly every week.

'There are bombings and assassinations nearly every week'.  And that constitutes 'a low level Islamic insurgency'?  So how, then, are we to define a high-level Islamic insurgency?  Bombings and assassinations every day?  Every hour? - CM
