Blitzkrieg means "lightening war". Blitzkrieg was first used by the Germans in World War Two.
Blitzkrieg was based on speed, co-ordination and movement. It was designed to hit hard and move on instantly. Its aim was to create panic amongst the civilian population. A civil population on the move can be absolute havoc for a defending army trying to get its forces to the war front. Doubt, confusion and rumour were sure to paralyse both the government and the defending military.
Once a strategic target had been selected, Stuka dive bombers were sent in to ‘soften’ up the enemy, destroy all rail lines, communication centres and major rail links. This was done as the German tanks were approaching and the planes withdrew only at the last minute so that the enemy did not have time to recover their senses when the tanks attacked supported by infantry.
From the Nazi Blitzkrieg of WWII to the Israeli Blitzkrieg being used against Gaza:
The Israeli War machine studied and copied the Nazi Blitzkrieg. The Israeli Blitzkrieg of Gaza is designed to foster a broad-front annihilation of Gazans and their towns.
Just like the Nazi Blitzkrieg, the Israeli Blitzkrieg of Gaza was designed to hit hard and to create panic amongst the civilian population, by killing and maiming as many as possible.
After the IDF Command had selected targets, American made F-16 fighter bombers and American made Predator drones were sent in to ‘soften’ up the enemy, destroy all of Gaza's infrastructure, targeting power stations, water treatment plants, sewage facilities, schools, mosques and health care facilities.
The Israeli Blitzkrieg was designed to install maximum terror in Gazans, since they have no way to evacuate the area, with Israel controlling ALL access points into and out of Gaza. Then came thousands of rounds of artillery shells, followed by waves of IDF Merkava Tanks, followed by Israeli Storm Troopers.
Don't believe me, see for yourself that the IDF has studied, copied and refined the Blitzkrieg tactics in this paper written in 1984 at the US Army's Command and General Staff College.
