No, that would be through the gospel, not through fleshly means. As Christians we do not fight like the world does.
“But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law.” - Galatians 5:22-23 ESV
“For though we walk in the flesh, we are not waging war according to the flesh.” - 2 Corinthians 10:3 ESV
What really happens though is evil men and imposters get worse and worse, and the world persecutes the church, for example here
Revelation 13:7
It was granted to him to make war with the saints and to overcome them. And authority was given him over every tribe, tongue, and nation.
The church has suffered much violent persecution and still is from all the world. The spiritual warfare your talking about 'pulling down strongholds', yes, but God does not always answer those prayers does HE in this lifetime, and does not apply to the world.
2 Thess 1
4 so that we ourselves boast of you among the churches of God for your patience and faith in all your persecutions and tribulations that you endure, 5 which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer; 6 since it is a righteous thing with God to repay with tribulation those who trouble you,
The restrainer mentioned in 2 Thessalonians 2, when he is taken out of the way, is archangel Michael, (not God or the church) who in scripture wages war with the devil-dragon-beast, as it says in Jude and Daniel regarding angelic powers waging warfare.
I am not ever going to run for political office, the RIGHT will always get my vote, simple because they are less evil than the alternative, and I and family have to live in this place a while longer.
Here is the context, notice verse 5 and 6...
3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare
are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6
and being ready to punish all disobedience when your obedience is fulfilled.
NOW what are the STRONGHOLDS? The world?? No. v5 and 6 is talking about believers every thought. We do not bring every thought of the world into captivity to Christ, that is impossible. This is talking about prayer for the church, building up the church and standing firm against the wiles and designs of satan against the church, as in corrupting the message of the gospel. Paul warned about fierce wolves coming in and tearing up the sheep, Peter wrote a lot about the false teachers in the church who will be among you.
That is what casting down strongholds is about.
