Matt 24 says not to be concerned when you hear about wars -- these happen because nations fight. It also says do not be concerned when you hear about earthquakes or famines; do not concern yourselves because these are the first pains at the start of a birth.
"You will hear of wars and rumors of wars; see that you are not alarmed; for this must take place, but the end is not yet. For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places: all this is but the beginning of the birth pangs. (NRSV)
Instead, the passage warns to watch out for religionists coming in Jesus' name saying they are the "Christs", the "Messiahs", that is, the "Anointed Ones".
"Beware that no one leads you astray. For many will come in my name, saying, 'I am the Messiah!' and they will lead many astray." (NRSV)
Hands up anyone who has heard of people being led astray by the "Anointed".
