At the end of the war in November 2012, the leader of Hamas, Khaled Mashaal, established the strategy of Hamas to destroy Israel based on two main and complementary elements: the army and politics. Mashaal suggested that the military superiority of Israel could be beaten by tactical military advantages, benefiting from Israeli vulnerabilities, reducing their military options through the use of political-legal tools and with the help of western leftwing organizations which “defend” the human rights. It is important to point out: launching rockets against a civilian population, intentionally, is a war crime. At the beginning of Operation Protective Edge 2014, the Israeli Defense Forces estimated that around 10,000 missiles filled the storages of Islamic Hamas/Jihad. Many of those rockets were provided by Iran and Syria or stolen from the Libyan arsenal. The Iranian war vessels delivered their weapons in the port of Sudan or Syria and from there they were introduced to Gaza through the tunnels crossing the border between Egypt and Gaza, specifically with Grad rockets and M-302 mortars. Sometimes, the trucks that transported the weapons were intercepted and destroyed by Israel.
The rockets included: 1) short distance (15-20 km): 1,000 units of self-produced rockets (15 km), 2,500 units of contraband rockets (15 km), 200 self-produced Grad rockets (20 km) and 200 contraband Grad rockets (20 km); 2) medium-range (up to 45 km): 200 self-produced Grad rockets and another 1,000 improved contraband Grad rockets (45 km); 3) medium to long-range (up to 80 km): more than 400 self-produced rockets. 4) long-range (100-200 km): about ten rockets. These are not rudimentary rockets. It is possible to suppose that currently (2019), Hamas possesses, at least, the same amount of rockets as in 2014.
