Islam causes most terrorism today. It is commanded in the Koran.
Terrorism is a tool - used by people who can’t use martial force.
They’d use military might if they still could,
but due to the economic poverty caused by their culture,
they cannot afford the force necessary to mount a direct military attack on free nations.
Back when hitech was horses and camels and swords,
they used military force to impose their beliefs on others.
Exactly correct. In 99% of the cases, modern terrorism is a tool to promote jihad. Jihad is not an aberration of Islam. It is one of the core tenets of Islam. It has been so for 1500 years.
