A more thorough explanation:

Ideological aggression is a type of propaganda that is used to spread ideas intentionally and deliberately in order to manipulate controversial attitudes and positions. It is hostile propaganda that is used by a state to incite and influence the people of another state to maintain or alter the institutions and policies of that state. This type of propaganda can be carried out by any means of communication and can come from within or outside the territory of the victim state.

• Hostile propaganda: This type of propaganda is used by a nation to manipulate the people of another nation to support or oppose their government. For example, a country may spread false information about another country's government to incite its citizens to rebel against their leaders.
• Subversive propaganda: This type of propaganda is calculated to incite a civil war or revolution. For instance, a group may use propaganda to encourage citizens to overthrow their government and establish a new one.
• War-mongering propaganda: This type of propaganda is used to produce national support for a war and to encourage the government to declare or join in a war regardless of any legal constraints. For example, a country may use propaganda to convince its citizens that another country is a threat to their national security and that war is necessary to protect their country.

These examples illustrate how propaganda can be used to manipulate people's beliefs and attitudes towards a particular government or country. It can be used to incite violence, rebellion, or war, and can have serious consequences for the victim state and its citizens.
