The war with Iraq lasted: 100 hours one week six days

Is that the question

imperialism is a type of government that seeks to increase its size, either by forcing (through war) or influencing (through politics) other countries to submit to their rule. the sun never sets on the roman empire, or so went the saying when rome controlled the majority of europe 2000 years ago.

2018 means 2018 ce or common era

there have been other eras too including bce, which included way more years.
